I don't want him at United, same reason I don't want Falcao. We have a good set of strikers now. A good mix of youth and experience. No need to change that.
I think he'd be better off going to Byern Munich though. He's clearly comfortable playing in Germany, Beyern are a very good side right now that would appeal to him (likely to be European champs too IMO), plus they've signed Gotze who he'll be familiar playing with and so can rely on service coming to him. Also, Beyern will likely need a new striker to freshen things up, with Gomez getting less game time than he's been getting in recent seasons, and Pizzaro now 34. I think that's where he'll end up to be honest, especially since interest from United has cooled compared to what it has been in the past, and that rumors of him going to Byern are still as strong as ever.
