Press Pass: Jose Mourinho exclusive
AC Milan vice-president Adriano Galliani has confirmed that he is to hold talks with Madrid president Florentino Perez over Kaka, though both Galliani and Rossoneri director Ariedo Braida have acknowledged that the player's salary would be a significant impediment to any deal.
Madrid are said to be keen to remove Kaka from their wage bill. It has been reported that the midfielder has been informed it is in his best interests to move on, but Mourinho, speaking after the 5-1 friendly victory over LA Galaxy, claimed he would be more than happy to accommodate him.
"For me, there is not problem. We will try to get the best out of him," he said. "He is a good player. He played well last season and helped us win games. Our hope is that he stays. As a coach I would be happy because he is serious, hardworking and contributes to the group.
"In some matches he is a great player, with quality and the ability to help us win. We know him well and have worked together for two years.
"He contributed well last season and I know what he has in his head. We do not need to send messages. The important thing is that he decides on his future that is ideal for himself."
