Terry, whose achievements on the pitch were often marred by his behaviour off it, told the BBC his defensive blunder in letting Etienne Capoue make it 1-1 should serve as a lesson to young children. We are not happy with the goals conceded, but we are pleased to get the win. "But hopefully I think this season has been really good for them, they're safe again and sometimes they play really good football". I didn't give up and today the team and I have been rewarded.
