I agree he seems to have application problems, I'd say LVG and Jose would have similar man management styles. He was such a talant at such a young age it would be criminal for someone not to try and drag it out of him.
I don't know. Attitude and commitment is a very big part of what makes someone a talent. If they're not quite perfect you can work with that, if as has been implied with Shaw, it's a constant battle to just get him to put the basic effort in, or even keep himself in shape, I don't really know what any manager could do.
Ferguson was great at getting the best out of players, but I couldn't see him doing much with Shaw. He tolerated similar from Tevez for a year or so (lazy trainer, over weight, etc.), but then ran into a similar situation that Jose is in now...and that's Tevez. I suspect the reason it was tolerated is because Tevez was still a good player despite the issues. Shaw is a decent left back, not a match winner. He can't really afford to take luxuries.
