As much as i hate to admit it i think the fans put more pressure on Obertan than anyone else, from the moment he's supposed to get the ball till he gets it and lets it out of his feat everyone is shouting at him.
Then again he's being payed millions to play football infront of them so he should be able to handle it. personally as pissed off as i was at him i didn't really do anything when he came off, however i understands people's frustration with him, he needs to sort out his act.
