Manchester City fullback Gael Clichy admits Sheikh Mansour wants to win the Champions League.

City face falling short yet again this season after defeat to Barcelona this week.

"We are privileged to be in a club like this that wants to improve year after year. And to improve is to go further in the Champions League," Clichy said. "Twice in a row we are playing Barcelona, they are a big team and know how to play those kind of games.

"I think eventually we will get there. Those clubs have been built for several years, 20, 30, 40 years, and this is only the sixth season for us. That's no excuse. We have to improve. The owner wants [us] to improve quickly so we have to improve quickly. If we play as we did in the second half, everything is possible."
