Can't be arsed arguing, but he played well today. He came on to do a very specific job and that was the work the opposition when in possession. He played the role of a defensive forward. He did very well in that respect.
Once again, a lack of goals is blinding people to his actual play. Even for Mirallas goal he made the correct run to the back post to pick up the effort if it was dragged across, and if Anichebe hadn't shot wide when the blatantly obvious ball to Jelavic was on then we'd be talking about a Jelavic goal today.
