6. Dimitar Berbatov: £30.75m from Tottenham Hotspur
Some people may find it harsh to see Berbatov on the list, but the Bulgarian didn’t match his £30m price-tag during his career in Manchester.
After a superb career at White Hart Lane, the striker secured a mega-money move to Old Trafford, and during his four year stint with Sir Alex, he managed to make 108 appearances, scoring 48 goals.
However, despite his good scoring ratio, Berbatov’s attitude and style of play didn’t win over Sir Alex and he spent most of his time at Old Trafford on the bench.
