What do you mean suit James' style?
He's a magnificent playmaker who can pick an eye of the needle pass, whether over 10 yards or 60. He can play anywhere behind the strikers as we've seen this year. He can run games and find space without having to sprint.
Good players, of that level, fit into any 'style' of play more often than not, other than in certain games (Leeds away being a good example where it's about man-marking).
You don't think James wouldn't benefit from having a winger with actual pace and tenacity to pick out, and for us to stretch teams? You don't think we'd be better with James being able to ping balls to either full-back and those full-backs know they can get up and down? You don't think he'd benefit from being able to play upfield, like he did at the start of the season, and have a ball-carrying midfielder to get the ball forward to him so he doesn't have to drop back to the centre circle.
Issue is, we have a load of other players who can't run, can't carry the ball, won't pass anywhere other than backwards, rely entirely on James to create if he's there and if not it's give it to Digne or try win a set-play - and that falls on the manager too.
We got him on a free, and he's not relatively on massive wages for a PL club. We have Bernard earning about as much and he contributes f all, Iwobi on 70/80k a week to fall over, Gomes on 100k a week to pass back every time he gets it.
We've got a sprinkling of star dust which hardly any other teams outside the established scum six have. There's pretty much Grealish and that's it, and he's at Villa because they produced him - their once-in-a-generation academy talent. We now need the other quality around the lad so that when he is fit, he can be even more productive, and when he isn't, we aren't totally inept.
