Rooney was leaning forward, and yet he lost his balance, you definitely can see him trip a bit, but he still managed to do a 45 degree turn and stepp backward. The guy to Rooneys left as he is fighting through is touching his shirt while the other defender grabs his shirt a little more, though Rooney has his arm thoroughly rapped around the guy to his right. The fact that its 2 guys on one is definitely unfair, but im still not sure about that step.

Still, its a dodgy decision, while not even being sure for what it was, we dont even know if it was justified.
