It depends on the team and the league, he wasn't a "Bomb" when he was in the bundesliga, which is why ManU was attracted to him. So coming back may not be a bad choice. He is hungry to prove himself again. Media is crap many times assuming one thing has to do with the other. Alot of players may struggle in another league and at ManU. They have been a crap team recently anyway.
