The FA Cup finalists were alleged to have been unhappy with Ballack's decision to have an operation to repair his damaged ankle but the club have now made it clear that surgery was undertaken with everyone's full agreement.

Ballack injured his ankle in the goalless draw with Newcastle and will miss the Cup final against Manchester United even though he is now back in light training.

A statement from Chelsea read: "In answer to recent speculation regarding Michael Ballack's injury, nobody's future at Chelsea Football Club was ever in doubt following his operation. There is also no doubt that Michael has put Chelsea FC's interests first.

"On speculation regarding the diagnosis of the injury, this has never been an issue. There was a debate on when an operation should take place, and there was a final agreement on that surgery taking place.

"Chelsea and all its players have full confidence in our medical team headed by Bryan English and his professional reputation.

"All parties involved have discussed these issues and endorsed this statement. There will be no further comment from anyone."
