Summer Transfer Window Series: 10 Best Bargain Buys

As any football chief executive will undoubtedly tell you, laced among the big money moves and the anonymous acquisitions are the gems, the one in a million transfers. Though often not involving large sums, these buys didn't shake the footballing world when they happened, but would have far wider implications for the club, and the game, as time elapsed.

But, as with the other posts in this series, who makes my top 10? Who should be considered the best bargain buys?

10. Demba Ba - West Ham United to Newcastle United (Free, 2011)
Having made the move from Germany to East London in the January of 2011, Ba made an immediate impact for West Ham, scoring seven goals in 12 games to take the Hammers to the brink of survival. However, it was not enough, and Ba opted to leave for Newcastle. He would find his feet similarly quickly, scoring 16 goals in his first season as Newcastle narrowly missed out on Champions League qualification. After a strong start to the following season piqued the interest of Chelsea, Newcastle made a tasty £7m profit, in addition to their European appearance.

9. Alessandro Del Piero - Padova to Juventus (£2m, 1993)
Arguably the best example of a young signing coming to fruition for his new employers. At the age of 16, Alessandro Del Piero was an up and coming Padova youngster, and despite having only scored one goal in 14 games for his first club, Italian giants Juventus saw something in him. In the summer of 1993, they paid just £2m for the services of a player who would go on to become a club legend.

Over the next 10 years, Del Piero would score 208 goals in 513 appearances for The Old Lady, racking up six Serie A titles, a Coppa Italia and a Champions League victory. Such was his loyalty, he remained at Juve despite their relegation following the match-fixing scandal in 2006, helping the club reclaim its former glories.

8. Andrea Pirlo - AC Milan to Juventus (Free, 2011)
Juventus have also proven to be rather astute when it comes to signing elder statesmen too. In 2011, it was the general consensus that Andrea Pirlo was past his prime, having been part of the all-conquering team of the late 2000s that included the likes of Kaka, Nesta, Maldini and Shevchenko. However, Juventus, just like Del Piero, saw the potential that Pirlo could provide, and made an inspired free purchase. The midfielder would go on to claim four Serie A titles - double that achieved for AC Milan, in addition to leading Italy to the final of Euro 2012.

7. Frank Lampard - West Ham United to Chelsea (£11m, 2001)
To suggest that £11m is a bargain buy, particularly in 2001 when prices were comparatively low, is perhaps surprising. However, with the benefit of hindsight, I think there are few Chelsea, or indeed football fans that would disagree. Already with considerable experience, having played almost 150 games for the Hammers, scoring 24 goals, Lampard completed his £11m move to Chelsea. And, as they say, the rest is history. 429 matches and 147 goals later, Frank Lampard is the club's all time leading scorer, and second in the Premier League's all time assists table.

6. Cristiano Ronaldo - Sporting Lisbon to Manchester United (£12.24m, 2003)
Similarly to Frank Lampard, £12.24m seemingly makes it difficult to consider how this may become a bargain. However, while Ronaldo may not have the longevity to match Lampard, he certainly made one hell of an impact at Old Trafford. At times mercurial, and at times petulant, the Portuguese magician solidified himself as one of the best players in the world, scoring 84 goals in 196 games for Manchester United. It was therefore unsurprising when Real Madrid came in for the winger, giving United a £68m profit.

5. Joe Hart - Shrewsbury Town to Manchester City (£600,000, 2006)
When Manchester City, perennial Premier League strugglers, bought an unknown young English goalkeeper called Joe Hart in 2006, few could ever have predicted the way it would turn out. Through all of the changes surrounding the Blues in the last six years, one thing has remained constant - their number one. In his 236 games for the club, he has had many memorable moments, whether it's keeping City in games against Borussia Dortmund or Barcelona in the Champions League, or his iconic arms outstretched run around the Etihad to celebrate Sergio Aguero's last minute Premier League winner in 2012.

4. Ole Gunnar Solskjaer - Molde to Manchester United (£1.5m, 1996)
Bought in 1996, Ole Gunnar Solskjaer was one of Sir Alex Ferguson's more underwhelming signings. Rather unknown and unproven, he was signed as a backup to Andy Cole and Eric Cantona. However, it was here he made his mark, quickly earning the reputation as a 'super-sub'. Though a moniker few footballers want, the Norwegian proved adept at scoring off the bench, scoring 18 in his opening season. He will perhaps be best remembered for his 1999 winning goal in the Champions League final against Bayern Munich, but in his 11 years at Old Trafford, he more than made back his £1.5m - scoring 91 goals in 235 games for United.

3. Gareth Bale - Southampton to Tottenham Hotspur (£5m, 2007)
Coming from Southampton's famed youth system, much was expected from what was a flying Welsh left back. Bought by Spurs in 2007, Bale always looked to possess talent, but it was only after a number of years in North London that the Welshman demonstrated his full potential. Having moved position into midfield to help Spurs into the Champions League, Bale terrorised full-backs across Europe, particularly on one night in Milan, where he put on a remarkable display in a 4-3 defeat to Inter. He picked up where he left off the following year, claiming the PFA Player of the Year Award, before a world record move to Real Madrid, earning Spurs £80m profit.

2. Thierry Henry - Juventus to Arsenal (£11m, 1999)
There are very few transfers that radically change the history of a football club, but when they do, you have to consider them a bargain, almost regardless of price. When Thierry Henry arrived at Highbury, Arsenal were a side on the back foot. Having lost the Premier League title to Manchester United, they signed the Frenchman who, disillusioned at Juventus, was designed to play as a central striker. Though £11m seemed steep at the time, Henry has surpassed everyone's expectations. In the following eight years, he led the club to two league titles, including the iconic 'Invincibles' season, three FA Cups and a Champions League final. Despite his short stay, he scored 174 goals in 254 games, making him Arsenal's all-time record goalscorer.

1. Peter Schmeichel - Brondby to Manchester United (£500,000, 1991)
Simply the greatest goalkeeper of the Premier League era, and to think that he cost just half a million beggars belief. It's not even like Schmeichel was particularly young - he was 27 when Ferguson brought the Dane to Old Trafford. However, Schmeichel proved the bedrock for the successes of the Red Devils through the 1990s, and arguably kept Ferguson in a job in the early years. In 292 games for United, Schmeichel won five league titles, three FA Cups, a league cup and captained United to the Treble in 1999.

So, as we can see, for every misguided and inflated transfer fee that Sir Alex Ferguson paid over his decades in charge of Manchester United, he found a number of gems, which formed the heart of his dominant side in the 1990s and 2000s.

Club legends, as one would expect, are almost impossible to predict on purchase, but is there anyone bought so far that has the potential? Perhaps not the big money transfers of the likes of Raheem Sterling or Memphis Depay, but certainly mid-range signings like Georginio Wijnaldum or Xherdan Shaqiri have promise.

Summer Transfer Window Series: 10 Big Money Flops

With the recent commercialisation of global football, money has rarely been an issue for the largest teams. As a result of this, we've seen a period of valuation inflation when it comes to transfers, with some enormous sums of money flying around. Some of these make my 'Transfers that Shook the World' post, while others sneak under the radar. In addition, sometimes the money is justified by performances (for instance, Ronaldo's £80m doesn't seem too outrageous any more!), while others end up being an enormous waste of money.

But which are the biggest waste of money? And are there any trends that we can see when it comes to clubs and overpaying?

10. Robbie Keane - Tottenham Hotspur to Liverpool (2008, £20.3m)
A great example of a big money transfer dropping under the radar. In 2008, Robbie Keane made the move away from Spurs, a club he'd spent the majority of his career to that point with. Daniel Levy, as he so often does, managed to get an exceptional deal for the North London club, costing Liverpool £20.8m for the Irish international. However, the proven goalscorer proved to not be so prolific in red, waiting 11 games for his first Liverpool goal. He went on to only score five goals in 19 games for the side, though they did manage to recoup much of the fee they paid for the striker when he returned to Spurs just six months later.

9. Angel di Maria - Real Madrid to Manchester United (2014, £59.8m)
Though the Argentine made the back end of my 'Transfers that Shook the World' post, he has failed to make the desired impact. He ends up lower down this list because of the fact that he's only been there a year, and I tend to give players a second season to take effect. However, with it looking increasingly likely that di Maria is on his way out of Old Trafford, the four goals and ten assists provided last season just isn't worth the money paid.

8. Dimitar Berbatov - Tottenham Hotspur to Manchester United (2008, £30m)
Back on that crazy deadline day in Manchester in 2008, it was the £30m signing of Dimitar Berbatov that paled into significance following the Robinho saga across the road. Manchester United, despite the wealth of attacking talent at their disposal, with the likes of Ronaldo, Rooney and Tevez all in form, dipped into their coffers to add another proven Premier League goalscorer. However, the big Bulgarian was always on the periphery, failing to rediscover his form and finding his most successful moments at Old Trafford in the cup competitions.

7. Diego - Werder Bremen to Juventus (2009, £23.8m)
A player who was among my favourites at Werder Bremen in my teenage years, Diego set the Bundesliga alight with his guile, creativity and flair, leaving many of the world's top clubs vying for his signature. Italian giants Juventus won the race, with the Brazilian signing for £23.8m in 2009. However, in 33 games, he managed just 5 goals, and was deemed to be surplus to requirements by the end of the following season, recouping just £12m when he moved back to Germany with Wolfsburg.

6. Mario Balotelli - AC Milan to Liverpool (2014, £15m)
Why always him? The enigmatic Italian had the world at his feet when he broke onto the scene in 2008 at the age of just 17, but his childish attitude garnered him a reputation both in Italy and in Manchester. However, there was no doubting his ability, and Brendan Rodgers looked to have pulled off a masterstroke when he signed Super Mario for just £15m last summer. To be fair to Mario, he certainly had seemed to work harder for his team, and improved his attitude, however, he just didn't have the goals. Mocked repeatedly for failing to score throughout last year, his days look numbered following the arrival of Christian Benteke last week. How much they can get for him remains a mystery.

5. Alberto Aquilani - AS Roma to Liverpool (2009, £17m)
AS Roma's 'Little Prince', seen as the natural successor to club legends Francesco Totti and Daniele De Rossi, made the difficult decision to leave his home town club in 2009, opting for Merseyside in a £17m deal. However, a series of injury problems and inconsistent form limited his opportunities in the team, with the Italian making just 18 appearances over an unsuccessful three year period while making loan moves back to Italy with Juventus and AC Milan, before a permanent free transfer to Fiorentina in 2012.

4. Juan Sebastien Veron - Inter Milan to Manchester United (2001, £28.1m)
The Argentine world beater's £28.1m move in 2001 was a club record transfer at the time, and underlined United's intentions to create their own Galacticos. However, it was not to be. Unlike the Italian game, Veron struggled to get to grips with the speed and physicality of the Premier League, scoring just seven times in 51 appearances for United. Such was his failure, Sir Alex Ferguson, who had publicly defender Veron on numerous occasions during the following season, sold him to Chelsea for a cut-price £15m in 2003.

3. Roque Santa Cruz - Blackburn Rovers to Manchester City (2009, £17.5m)
Very much like the signing of Dimitar Berbatov, Roque Santa Cruz was brought into a Manchester City squad already containing the likes of Carlos Tevez, Emmanuel Adebayor and Robinho. However, even worse, they had signed both Tevez and Adebayor for large sums in the same summer, making the purchase of Santa Cruz even more pointless. Though certainly only bought as Mark Hughes was his manager at Blackburn Rovers, the Paraguayan only managed three goals in an appalling 20 game stay at The Etihad, before being farmed out to Blackburn and Malaga on loan, before moving permanently to the latter in 2013.

2. Kaka - AC Milan to Real Madrid (2009, £55m)
Kaka, arguably the world's best player in the mid-2000s, leading AC Milan almost single-handedly to a Champions League title in 2007, became the first of the new Galacticos signed in 2009, being joined by Cristiano Ronaldo and Karim Benzema. However, he never hit the same heights as he did in Italy, scoring 23 in an injury hit four seasons, which saw the Brazilian make just 85 appearances before rejoining AC Milan.

1. Andriy Shevchenko - AC Milan to Chelsea (2006, £30.8m)
Another world class forward player from AC Milan makes a disastrous move abroad for an astronomical sum - I guess this proves that Silvio Berlusconi got something right, cashing out at the best moment. Ballon d'Or winner Andriy Shevchenko made the move to London in 2006 for £30m, joining up with Jose Mourinho's two-time champions as Roman Abramovic targeted the Champions League title. However, nine goals is not enough for just one season for a top striker, never mind being spread across three years. Every goal scored by the Ukrainian at Chelsea cost over £3m, which everyone would agree is expensive!

So what trends can we see from these ten? Firstly, it seems that for all of his good signings (Vidic, van Nistelrooy and Ronaldo etc.) Alex Ferguson also wasted an awful lot of money, and Louis van Gaal appears set to do the same. In contrast, both AC Milan and Tottenham Hotspur seem good at getting the best deals for their players, in addition to selling them at the right time - just as they go off the boil.

And are we likely to see any big-money flops this summer? Of the transfers already done, it seems unlikely that either Arda Turan or Arturo Vidal will fail to live up to their valuations, while though it pains me to say it, Raheem Sterling may well struggle to meet the £49m valuation placed on him. Similarly, £60m and £70m valuations for Kevin De Bruyne and Paul Pogba also runs the risk of making this list, as they would have to go some to make the deal worthwhile.

Nevertheless, it's worth noting that a high profile failure can have a disastrous impact on a player's career - will Angel di Maria be able to make his seemingly inevitable move to Paris Saint Germain work to be the exception to the rule?
