In my opinion his actions regarding his contract, irrelevent of the involvement of Kia, has moved him back to square 1, i.e. he no longer has hero status but I do not view him in a negative way, from his hard work and effort for the club I feel we owe him that much at least. And so I will give him the welcome that any city player deserves when stepping onto the pitch.
On another note I do not feel he should be playing as captain, since as others have pointed out, the captain should lead by example and be fully in line with the clubs ambitions. I also believe that he shouldn't have got it in the first place.
