Young is ok but he really needs to knock the bitching/moaning out of his game, If he spent less time bitching/moaning & actually playing the game he might get better.
As with SO many England players, there seemed to be a seeming identical timing of his first England call ups to his embarassing diving suddenly appearing in his game. This seems to have happened to LOADS of england players who seem to be being taught its part of the game and not getting involved in it is denying your team a viable source of goals. A good manager should, like Ancelloti/Drogba, knock it out of his game by simply telling him its not on.
I don't rate Young now as highly as I did 2 or 3 years ago. I'd rather have a fit Lennon in my team (dependant on what my strikeforce looked like).
Yes and no, he's not as good as a few years ago, simply because the team are much much worse than 2-3 years ago.
When your primary role in the team is creating chances for others, when others can't put them in the net you look bad. So often people will say Fabregas had a bad game, purely because he'll put a chance on a platter 10 times in one game and the guys upfront won't put them in the net, another game he'll create less chances with less good passing, but will get 2 assists and be hailed for his best game of the season.
I like Young a LOT less since his diving antics, though he was horrific with diving last season(or was it very early this season?), though I haven't seen him being as bad lately, maybe Houllier has told him to stop it. I haven't watched an immense amount of Villa games this season.
Young at one of the better teams in the league would be, honestly, phenomenal.
AS for defensive duties, you really should watch Villa(when and if Houllier stops playing him as a striker, no idea why he is), he really does make a ridiculous number of excellent tackles in the box. Bellamy was the same, just a complete workhorse, doesn't matter where the ball is on the field both of them are 100% effort every minute of every game they play.
