Don't think he can do much about a lack of quality other than make sure we don't spend money on players who don't belong on the big stage. I think that's the mistake we made this summer. Some of that is on him though.
Honestly think the reason it hasn't worked out for him here is partly down to him wanting to be back in London. Probably we should sell, but only if they are willing to stump up a reasonable fee. $25m+ at least in today's market IMO.
