Yeah, I'm sure he's good enough for United.
But as a wide player, he's different to the ones they've had over the years, Park is more like Dirk Kyut so I don't see the comparison while Nani, Young and Valencia are closer to being out and out wingers which is the type Ferguson prefers. Of course he might just like the tactical flexibility of having someone different available to him.
Reports say that he'll decide his future after the German Cup final and the German newspaper that linked us to Podolski think that Kagawa will be United bound, so you may be right KAmi.
We've not been linked with him at all, which is a bit strange.
