7) Kolo Toure
Another of Arsene Wenger’s discoveries, Kolo Toure’s early days at Arsenal were spent either at right-back or right-midfield, though the decision to move him to centre-back in 2003/04 proved a masterstroke as his rock solid displays helped the team win the title unbeaten.
8) Cesar Azpilicueta
Starting out as a right-back for Chelsea, Cesar Azpilicueta never looked like becoming a truly outstanding player, but somehow a move to left-back under Jose Mourinho has really seen him come into his own, beating both Ashley Cole and Filipe Luis to become first choice in the last two seasons.
