Think that was more about the fact that the team in general were shite at that time, and Barkley wasn't playing any worse than any of the rest of them tbh, it seemed like Moyes was pushing the blame on to him a bit, that's how i saw it anyway, others may have a different view.
Hopefully it will have made a difference to Ross's game, although he does still look a bit raw, i think let him have a run against the smaller teams, and then give him 15-20mins against the bigger ones.
