Yes it was, his jersey was pulled, while there's a lot of "divers" in football Messi isn't one of them. He just wants to get on with the game, he is one of the most fouled players in the Barca squad!
I was only trying to be amusing Chewn. It reminded me of a game where a player complained, "That was never a penalty, ref", receiving the reply, "Read tomorrow's papers and you'll find out that it was". :-)
Thought i'd already explained that, davetuc. The first 'foul' contact was outside the box, contact continued into the box and Messi went down. Obviously without the benefit of instant replays, very difficult for officials to get it spot on - if you'll pardon the pun:-)
