Manchester United are monitoring Kaka's situation at Real Madrid.

AS says United and Manchester City have joined Chelsea in making tentative enquires about the Brazilian's availability at Madrid.

Kaka is unsettled in Spain after a disappointing first season plagued by injury and accusations of putting his World Cup hopes ahead of Real.

Chelsea are favourites ahead of United and City for Kaka thanks to his relationship with former AC Milan coach Carlo Ancelotti.

Jose Mourinho is expected to have final say on Kaka's future once he is appointed new coach next week.
