Sadly, I have to agree with Mike and Han. I love Oba and will always follow him, wherever he ends up, but he's built for Premiership where there is a helluva lot more space to operate for a player of his characteristics. In Italy, it's so much more "confined" and the opposing players rarely give you any time on the ball.
There would be no reason to bring him back anytime soon. Ibra, Adri (finally rounding into form), Crespo, Cruz and when he's healthy, Chino. Possibly the best group of forwards in Europe.
