Chelsea crisis not over, says Petr Cech

PRAGUE (AFP) - Chelsea goalkeeper Petr Cech said on Wednesday his side's 3-1 Champions League defeat to Napoli was a sign the English Premier League side's crisis is far from over.

Injury-plagued Chelsea are already struggling in the league and the FA Cup, leading to media speculation that club owner Roman Abramovich is looking to replace manager Andre Villas-Boas.

After Tuesday's defeat in Naples, the London giants now face a tough call to save their last 16 tie in the March 14 second leg at Stamford Bridge.

But while Cech believes the Blues can overcome that setback, the Czech international lamented the 'silly mistakes' that have given Chelsea a mountain to climb in three weeks time.
