Inter boss Jose Mourinho admits he was happy Kaka snubbed Manchester City last week and chose to stay with AC Milan.
"I am happy that Kaka didn't go there," he said. "I want the best players to be in my league. I want my league to be as strong as possible and of course Kaka is absolutely top.
"It would have been very, very bad for Italian football if Kaka had left Serie A.
"When a player like him decides to join City it will be because they have proved there is a big project; because I don't think a player like Kaka is going to leave a club like Milan because of one euro more or one euro less."
