7. Frank Lampard – West Ham United to Chelsea – £11 million
Lampard was part of a golden generation of talent being produced at Upton Park in the late 90s, and once the club were relegated in 2001 Chelsea were able to prize him over to the other side of London for a meagre £11m. The anger of the Chelsea fans at the time seems funny now, as Lampard went on to lift three Premier League titles, four FA Cups, two League Cups, one Europa League and one Champions League. And if that wasn’t enough he became the club’s all time leading top goalscorer. Not bad for £11m.
