3. Cesc Fabregas to Chelsea, 2014 – £28.6m
Formerly the captain of the Gunners, the 27-year-old has made his return to England following three frustrating years in Catalonia with his boyhood club.
Fabregas made his name in North London and prompted his former side to buy him back for £29m in 2011, but the Spain international never truly established himself and is now back in the English capital.
