Chelsea chief executive Peter Kenyon has reacted angrily to the claim made by Real Madrid president Ramon Calderon that he has held talks with with Arjen Robben about a possible move to Spain.

Kenyon says they intend to report Real Madrid to Fifa over what they deem to be an illegal approach for Robben.

“We note that Mr Calderon confirms Real Madrid spoke to Arjen,” said Kenyon.

“As a result Chelsea will be writing to Fifa to ask them to investigate an illegal approach by Real Madrid.

“There have been no meetings or conversations between the Real Madrid sporting director Predrag Mijatovic with any Chelsea officials, anyone mandated to act on Chelsea’s behalf or owner Roman Abramovich about Arjen’s future.”

Earlier today Calderon revealed that he had spoken to Robben about a move to the Santiago Bernabeu.

“We are in discussions with Chelsea and the player, they are at an early stage but we hope to sign him,” he said.

“Bringing Robben was one of my pledges when I was running for president and still remains the case.”

Robben recently claimed he had turned down the chance of a move to Bayern Munich and was on the verge of signing a new deal to keep him at Stamford Bridge until 2012.

His impact at Chelsea has been restricted by a succession of injuries, and last season he missed large parts of the campaign through thigh and knee injuries.
