according to one website, that's the only serious injury he's ever had (ankle injury i think), and it ruled him out for about 4 months, so not most of the season. don't think it's anything to worry about.
as for the 'style of play' thing - what exactly do people want? if you think we'll suddenly start playing like barcelona then you'll be bitterly disappointed. likewise, our style will naturally improve with more technical players involved. this 'style of play' thing really grinds with me. you have to go through the right stages to become a better side defensively, just as you have to go through certain stages to become a good attacking force. hughton is not a negative manager, nor is he an attack-minded god - he is somewhere in the middle and those in the middle tend to be more successful as they get the balance right.
