Manchester City boss Roberto Mancini was upset for Jack Rodwell after injury forced him off in victory at Aston Villa.

Rodwell limped out of the action with a suspected recurrence of a troublesome hamstring injury which has plagued his first season at the Etihad Stadium.

"Jack is very unlucky because he was playing really well, it looks like he will be out for another three or four weeks" Mancini said.

"I was so happy with his performance against Chelsea and again tonight but it looks he has a hamstring problem again."
