Only reason why the whole diving thing with him has become more apparent is because of the exposure Man Utd gets. Like a few people on here have said already, I don't think he started diving more since he joined utd.
When he was playing for us, he was genuinely getting clipped while being too fast for people but then realised how to dive "correctly"....if that makes sense?
Anyway, if the option was there to bring him back, then why not? He'd want to be on that plane to the world cup with the England squad. Failing that, bring in Zaha!
But, it won't happen, and we'll probably sign someone like Popov, who we've been linked with.
