#4 Diego Forlan
Forlan won the Pichichi top goalscorer award in the La Liga twice, the European Golden Shoe and the World Cup Golden Ball with Uruguay, but his time in the English top-flight with Manchester United can’t be classified as anything other than miserable.
Forlan earned a fearsome reputation in Argentina with Independiente, having scored an impressive 40 goals in just 91 games. His form attracted the attention of the Red Devils, and he moved to Manchester in 2001 for nearly £7 million.
At a time when United were fighting it out with Arsenal for the title and desperately needed someone to carry the goalscoring burden of the team, it took the striker an astonishing eight months and 29 games to break his duck. He managed to score a meagre 10 goals in a total of 63 appearances in the league.
While Forlan’s top-flight journey was largely forgettable, he would go on to much greater things in Spain with the likes of Villarreal and Atletico Madrid.
