We all knew he suited Dortmund's style of play...
Back to front quickly, playing pretty much as a second striker which less emphasis on him dictating play, etc..
Not much we could do. The best thing that could have happened was never signing van Persie.
Kagawa and Rooney (and Welbeck?) up top, playing with lots of movement. Focus on getting the ball from back to front quickly.
Not only would we have seen a better Kagawa, but also a better United probably.
Instead, we attempted to control games slowly, which half of the players couldn't do well, and pretty much stopped counter-attacking.
I really think it could have worked out, but oh well.
