I've been saying the Coleman thing for ages now, he simply is not good enough, he was found out after a season, at £60k it was worth a gamble, but i really think he is lacking in a few major departments.
As for Osman, if he had any kind of consistency to his game, he certainly wouldn't be playing for us he would be playing for a team in the CL, the guy has skill in abundance, but he will have one amazing game, then vanish for the following 2 games.
