Chelsea midfielder Oriol Romeu believes that the Blues can prove their worth with a defeat against Manchester City this weekend.

The former Barcelona playmaker, who featured in Chelsea's 3-0 win over Valencia in the Champions League on Tuesday, hopes that he can retain his spot in Andre Villas-Boas's side.

"It's a great chance to show everyone what we can do when we are playing well," The Mirror quotes Romeu as saying. "If we win [against Man City], it will prove that we are still fighting for the league.

"I do not want to isolate one major threat for City. They have a lot of good players going forward. They are playing very well."

The Blues will face Roberto Mancini's side on Monday, who were knocked out of the Champions League last night.
