No, he is absolutely not overrated by common football supporters. At the moment I would rather say that he is underrated as he has been sacrificed to make room for Ronaldo this season, and people tend to have an extremely short-term memory regarding football. However, I wouldn't want to bring him to the red side of Manchester as he will be very expensive and not fit perfectly into the positions we need to improve. However, I fear that he would be absolutely immense City. Could fit nicely into Real Madrid or Liverpool as well, if they change to a 4231 formation with him behind the striker.
