Petr Cech has insisted that Chelsea are still in the Champions League despite their 3-1 defeat to Napoli in midweek.

The Blues took the lead at the Stadio San Paolo through Juan Mata before Ezequiel Lavezzi, who struck twice, and Edinson Cavani gave the hosts a two-goal advantage ahead of the second leg. However, Cech maintains that the tie is not over.

"We work hard as a team but we make mistakes where we concede spaces so the opposition get chances," he said.

"We have a talented team and we have been working hard on the training ground, but we have not been able to transfer that onto the pitch.

"We don't have much time to recover because there are a lot of games coming up. In the Champions League we have a two-goal disadvantage to overcome but we are still in it and we will fight."

Meanwhile, the Blues have slipped to fifth place in the Premier League.
