10) Santi Cazorla
One of the bargains of the last five years, Santi Cazorla joined Arsenal from Malaga for just £12m in 2012 and is certainly one of Europe’s best midfielders.
9) David de Gea
After a slow start, David de Gea really grew into his role at Manchester United and is now considered perhaps the best goalkeeper in the world.
8) Diego Costa
A title winner in his first season with Chelsea, Diego Costa was a great buy from Atletico Madrid, suiting the Blues’ style of play perfectly.
7) Alexis Sanchez
Arsenal’s best player, Alexis Sanchez was a brilliant signing from Barcelona, making one wonder why the La Liga giants ever considered letting him go.
6) Juan Mata
Bizarrely let go by Chelsea in January 2014, Juan Mata was a world class signing from Valencia and has continued to shine since moving to rivals United.
