Manchester City midfielder Yaya Toure admits finishing the season potless is unacceptable.
Toure is gutted over the way their season has tailed off.
"It will be hard for us now as our fixtures are very hard but we must not let ourselves down," he told the Daily Mail.
"We must fight for our manager Roberto Mancini, but also for the club because the club has invested a lot.
"We have to be realists. We have to win something this year as we have a fantastic squad. To win nothing isn't acceptable. But I am keeping my confidence.
"I am sure we can give Manchester United the right fight. It's not finished yet."
