Real Madrid ace Kaka is finding himself under increasing pressure after suffering criticism following his struggle to gain full fitness at the club.
El Mundo Deportivo claims the Brazilian is unhappy with the situation after being derided by the local press in Madrid, who seem to have run out of patience.
Kaka is said to have told president Florentino Perez he is tired of the negative spotlight being focused on him, after being told he would be out of action for at least another 15 days due to a further problem on the knee he had surgery on last year.
After already being out for eight months, voices in Madrid have started to renew attacks on his €65 million transfer from Milan in 2009.
However, the 28-year-old told Perez he would not give up the fight to overcome his injury battle, only for the chief to respond he would not wait forever.
The latest reports seem to have heightened speculation over a summer exit which suggested he would smooch back up with former club Milan, and on Wednesday, EMD claimed Kaka had a agreement with Milan over a cut-price summer deal.
But, Milan CEO Adriano Galliani, and transfer consultant Ernesto Bronzetti both said a move back to the San Siro was "impossible".
