No. What is written in bold is what it says on the tin. He needs to get himself fit. He was sluggish in preseason and, for whatever reason, has missed at least 2 week of training with the squad. He needs to work hard over the International break to get his fitness levels up.
As regards the transfer window, what have we actually done this window that is so great? Everybody on here will probably agree that we had a poor window, and many would actually say it was a catastrophe. Certainly going by last nights comments in here. So saying that he was the best thing to happen in the window is no great shakes. Plus I even added the caveat "unless Gray continues his fine form" He's started great but I'm not going overboard about him after 3 games. But if he keeps it up then it's been an inspired signing for such a low fee.
As regards downing tools you really have as much clue as I do over what really happened. But I do agree with the general point you make. I call it unreliability. I think James will be disturbed by the lack of interest in him this summer on the back of being omitted from the Copa America squad, and will be sensible enough to realise that the only way to get his career back on track is to knuckle down and get back into contention here. That depends on his own motivation levels, so I guess we'll see.
