Mario Balotelli Could Have Played His Last Game For City Against Arsenal

After getting sent off in overtime against Arsenal, Mancini suggests Mario Balotelli may have played his last game at City. This could just have been said out of frustration as City's title hopes were demolished, but with the discipline issues that have been surrounding Balotelli all season, Mancini might have finally had enough.
What did you guys think of the game? Should Balotelli be sold? Will Mancini stick around?
