The agent of Mario Balotelli admits the Inter Milan striker did walk out on training prior to his axing for the win at Chelsea.

Balotelli was frozen out of the squad for the Champions League trip to Chelsea and reacted angrily to the news.

"There is no war between (Jose) Mourinho and Balotelli. There is a rapport that certainly needs to grow and improve, but they are not at war," said Mino Raiola.

"Everything Mario does is put under the microscope and the media is going over the top here. This is a lad who lives under the spotlight and in my view he needs to get away from that."
