Rooney, I don't think FM can properly simulate a player like him who is defo a world-class striker but doesn't score that many goals, on my game he usually gets more EPL goals than appearances which is totally unrealistic
He hasn't been the focal point of United's attack except last season, where he clearly did well as it. This season he's playing deeper and a more creative role and Berbatov is the focal point, but I wouldn't say he's too overrated. Maybe slightly though.
