He's almost always out on his feet last quarter of a game, not just when he's supposedly carrying an injury. I'm bored with Petrov, he has to put so much effort in at the beginning of games to make an impression that towards the end of the game he's totally ****. If every player did that we'd have to use all our subs and whoever wasn't subbed would ****, like Petrov. Imagine every player busting their ass like Petrov does only to be **** with 15/20 minutes left, we'd concede 2 or 3 late goals most games.
Petrov has played better this season, I think because of the defensive manner of the performances giving him a bit more insurance, but to be honest he's the most overrated player I've seen at Villa for years. He's been an ok PL CM since nothing better, which is an achievement in itself, but he's nothing special.
