I've said similar when my teams players have overreacted too. One of my least favourite players of all time is Harry Kewell because of the diving he did in a red shirt. (When it was slightly less common).
Look, Darwin 100% to blame. Not only that but stupidly easily provoked into doing something incredibly idiotic. Andersen isn't the only player who would have dropped like he was shot in that situation, it's a symptom of the modern game. Still a little ****ish... But yeah, I'm not in anyway saying Darwin isn't the main villain here... Nor am I excusing the twats sending Andersen hate... Just saying he was a little bit ****ish in his reaction and I can see what upset some people. Personally, I rolled my eyes and grinned a little when I saw how he dropped. I found it mildly amusing.
