He clearly doesn't want to sit on the bench and it is something very normal for a player with his quality. With the signing of Amauri and with the things happened in the previous year (his argument with ranieri) its natural for him to want out. He wants a team were he will be considered as a starter. If the things remain like this leaving will be the best option for him. If something changes dramatically, he may reconsider it nobody knows...
I don't thing that he will go to a team outside france. Marseille or monaco or even lyon will be his next team...
