Stefan Savic has assured Manchester City fans he'll get better.
City skipper Vincent Kompany started a four-match ban that night and boss Roberto Mancini has indicated he would like a new central defender.
Savic said: "To replace Vinny, everyone expects a lot from you because he's our captain and leader. But I think I can do it. It's not easy but I'm getting more confident and I can do better - try and do everything for the team.
"I feel OK. As I'm playing more games I'll get more experience and confidence. I think as time goes on I'll do better."
