It's funny, everybody judging him and his situation off that Youtube clip. It's also clearly obvious that again people are voicing an opinion yet actually knowing very little about his situation, or how he's done so far for United.
Kagawa might have been let by his teammates sometimes but he's also let his team down frequently with poor performances. In Europe he always plays his best games, he has more time on the ball and it isn't as physical. However, when he plays in the Premier League he's poor. He's far too weak on the ball, and without the time and space you get in Europe, he just isn't, as yet, very good for us.
I like Kagawa, and would love to see him succeed here, but I think he should have stayed at Dortmund too, but not because he is too good for United (far from it) but because he just isn't suited for the premier league.
Unless he improves sharpish (which is hard when he isn't been given much of a chance, after not playing well when he's had them) I think a lot of United fans will be quite happy to take a decent fee for him, and cut our losses.
Oh, and to be clear, not in anyway am I defending players like Young from that video. He's the worst of the lot....
