He's still young. So he has time to develop. He can definitely pass a ball.
Unless Houllier was playing 5 at the back, Delph was definitely in midfield. But he has played left back the last 2 games. If he was playing 5 at the back, then I should quite watching football, as I watched the whole game and didn't notice.
AS for Houllier's Villa. I think they look a lot better under Houllier than they did under Martin O'Neill. More of an attacking force, fitter and attacking with pace. The results don't show this, but I watch a lot of Villa games as my Dad is a fan.
