If Dunne stays or goes he wont play as much as i can see Kompany being joined at the back with a decent signing (Lescott/Toure??? altho i am very worried that only the NOTW and The Mirror have linked us with Lescott and Toure! we've not been linked with any defenders by a solid reliable source yet!) and Onuoha will be the back up defender ahead of Dunne if anyone is suspended or injured!
Dunne, if he does stay, should stay as club captain! But on the pitch as a leader, an encourager, a bollocking giver, a motivator, an organiser and someone who led by example from his first touch of the ball and throughout the season - in his first season with us as a 23 year old!!! - Vincent Kompany has to be given the arm band!
