Real Madrid coach Jose Mourinho has warned Manchester City about their deal for Inter Milan striker Mario Balotelli.

Mourinho says there's no questioning his talent, but City boss Roberto Mancini will face a test man-managing Balotelli.

He said: "The guy has incredible qualities, but sometimes does not know how to use his brain.

"Let me give an example: When we played at home in the semi-final of the Champions League against Barcelona, he would not take the field. I threw him into the fray and Mario was static, not even giving a hand in defence."
