Inter Milan boss Jose Mourinho admits he has concerns over Adriano after he failed to return for training last Friday. He said: "This is not indiscipline or a joke, it is much more serious. The only thing I can do, with sadness and no anger or criticism, is to say nothing.

"We will have to wait and see how this all ends for him, but at this moment in time I am concerned about the man more than the player."

There was a hint of a problem when he commented he was not sure whether he would be renewing his contract with Inter, which expires in June 2010.

"The best thing is to respect the situation we all know, between moments of hope and the more difficult times," continued Mourinho.

"Adriano has been very important for this team and was crucial in certain moments. As for the squad now, we have some great strikers and so there won't be problems because of his absence. Our only concern is for him."
