Chelsea insist there's no fitness concerns for goalkeeper Petr Cech.

Thibaut Courtois, who was sent on loan to Atletico Madrid after joining from Genk, claimed the Blues' coaching staff had serious concerns about Cech's knees and back.

But a Chelsea spokesman said: "Petr is one of the best goalkeepers in the world, always performing at the very highest levels.

"The club has no concerns at all with any aspect of Petr's game or physical condition, and we expect him to remain one of the world's best for many more years to come."
