To be fair Theon, you've not so much gave an opinion but stated something you can't really know for sure as fact, and laughed at anyone who doesn't agree. For all we know Fergie could have signed Kagawa as a central midfielder. We've no idea what his plans for him are, or whether playing him will mean only playing one striker. He's played 2 minutes for us to date, nothing is clear yet.
If Fergie sees Kagawa as a midfielder then signing another forward player isn't beyond the realms of possibility, especially if Berbatov goes and Macheda goes on loan, which is likely. We were interested in Hazard while signing Kagawa, and appear to be interested in Lucas Moura, both attacking players, so perhaps Fergie's plan for Kagawa isn't as obvious as it looks. Yes, he plays off a front man, and has played there predominantly for Dortmund, but that doesn't mean that's where Fergie will use him. Anderson wasn't a central midfielder until he came to United.
