I think you have to accept players like them for what they are. Most of the loss of possession was down to be too eager to impress and general rustiness. You can tell he's chomping at the bit. To get those sorts of players into the team you have to be set up to do some of their work. Saying that when he was sharp and fit last season against Everton he didn't shirk the graft getting back on the left. I think he has some work to do to get in the team even if I thought Best was well below par yesterday.
Aye, his performance at Everton was incredible and I've no doubt he'll produce more like that in the future. I just think sometimes we have rose tinted glasses on with him a bit...Imagine if it were Ameobi who lost possession as many times as Ben Arfa did...
