The Premier League's 2014 summer transfer window brought in numerous huge talents, from Diego Costa to Alexis Sánchez or the return of Cesc Fàbregas.
However, as always, there have been some huge disappointments. We've tried to round the list down to the ten biggest flops of the season.
The criteria: 1 - A high transfer fee. 2 - High wages. 3 - Frequently poor performances despite regular appearances.
10: Filipe Luís (Atlético Madrid to Chelsea, £15.8m)
An odd signing. Despite already having in their squad César Azpilicueta and Ryan Bertrand, Chelsea decide to splash out on another left-back. What's more baffling is why Luís' form has dropped so sharply since leaving Atlético Madrid.
9: Jordon Mutch (Cardiff to QPR, £6m)
Mutch was impressive for Cardiff, and as a result, QPR spent £6 million to secure his services. It didn't work. He never scored, earned only one assist, and his performances were nothing short of abysmal.
8: Rickie Lambert (Southampton to Liverpool, £5m)
The future seemed bright for Rickie Lambert. Having scored 14 goals and assisted 13 more, Lambert completed a move to his boyhood team Liverpool for what seemed like a bargain fee of £5 million. Unfortunately, Lambert has dramatically failed to reproduce his Southampton heroics with the Reds.
7: Rémy Cabella (Montpellier to Newcastle, £12m)
The Frenchman's performances have slightly improved, but he's still a long way from justifying his £12 million price tag. It took him nine games to earn an assist and an incredible 23 before he scored. He's yet to add to those tallies. Watching him play, he looks talented, but lacks end product.
6: Adam Lallana (Southampton to Liverpool, £25m)
Big things were expected of winger Adam Lallana, and rightly so, having had a terrific season with Southampton. However, the England international's performances have been disappointing in comparison. His effort is unquestionable, but he just seems to lack a bit of confidence in his play.
5: Dejan Lovren (Southampton to Liverpool, £20m)
I was baffled by this. Liverpool's poor defence was the only reason they didn't win the title in 2013/14, yet they only signed one centre-back. In fact, they signed a frankly mediocre one, and for a huge fee.
4: Eliaquim Mangala (Porto to Manchester City, £32m)
This simply proves how much money Manchester City are pumped with each year. Having had a promising season for Porto, Man City splashed out £32 million on an inexperienced young defender. It was always rash, and City have suffered the consequences.
3: Radamel Falcao (Monaco to Manchester United, £6m Loan)
United signed Falcao for £6 million on deadline day, on a season-long loan with the option to buy for £43.5 million. The deal saw the Colombian striker earn £265,000 a week.
Falcao has excellent work ethic, and has assisted five goals this campaign, but he just seems to lack predatory instinct; that desire to get in behind and score.
As a result, Falcao's performances have been heavily criticised, and four Premier League goals tells you why.
2: Angel Di María (Real Madrid to Manchester United, £59.7m)
It's saddening and confusing to watch Angel Di María playing in recent months. Having been arguably the best winger in the world, the Argentine has simply deflated at United.
He started excellently; three goals and four assists in his first five games. Unfortunately, it's not been the same recently. He hasn't scored in almost five months, and was even subbed at half time in United's most recent game.
1: Mario Balotelli (AC Milan to Liverpool, £16m)
Having sold Luís Suárez, it was obvious Liverpool needed a replacement. Would it be the dynamic Alexis Sánchez? The pacey Pedro Rodríguez? The (formerly) prolific Radamel Falcao? No. Instead they signed Mario Balotelli, who's a classic maverick striker; no work ethic, individualistic, complacent and inconsistent.
Not the right signing, and so it has proved. No assists and four yellow cards all season, and it took him 25 weeks to score. Indisputably the flop of the season.
