Real Madrid boss Jose Mourinho is chasing Tottenham winger Gareth Bale.
The People says he hopes to tempt manager Harry Redknapp to do business by offering Lassana Diarra in a £25million deal.
Real Madrid manager Mourinho is desperate for a new left-sided player and has switched his attention to Bale after missing out on Chelsea and England's Ashley Cole.
