Chelsea owner Abramovich ready to bankroll bid for Real Madrid star Kaka
The pair had a very successful, six-year relationship and won the Champions League together in 2007.
And as he feels the heat in the pressure-cooker atmosphere that surrounds everything at Real, Kaka could be tempted to work with Ancelotti again in the relatively tranquil surroundings at Stamford Bridge.
While Cristiano Ronaldo has been a success, Kaka has only appeared sporadically - mainly due to a troublesome thigh injury.
There is a growing suspicion there might not be room for both galacticos in Madrid.
