John Obi-Mikel: 'Chelsea must improve quickly'

Chelsea midfielder John Obi-Mikel has admitted that losing to Basel in the Champions League was a "really bad" result for the club.

The Blues let slip a 1-0 lead to lose 2-1 to the Swiss side at Stamford Bridge, and Mikel believes that the club could lose to anyone if they don't improve on their recent form.

The 26-year-old told The Express: "If we play the way we did there, we have a chance of losing to anyone that we play.

"We go back to training now and must look at the things that we have done wrong and try to put it right. It was really, really bad – a very bad result for us."
