Chelsea have accused Real Madrid of making an illegal approach for Dutch winger Arjen Robben and will ask FIFA to investigate comments made by the Spanish club's new president Ramon Calderon.
The Barclays Premiership champions ran out of patience with the newly-elected Madrid chief who had boasted during his presidential election campaign that he could land Robben.
Calderon insisted that Robben wanted to join Madrid and that he had spoken to the player - claims which were firmly rejected by Chelsea last week.
But Calderon refused to accept Chelsea's stance and continued to maintain that Robben would join the club and that talks had been held with Blues owner Roman Abramovich.
His latest remarks stung Chelsea into an angry response in which the club's chief executive Peter Kenyon stressed the player was not for sale, that there had been no talks with Madrid, and that they would be reporting the Spaniards to FIFA for comments the London club believe constitute an illegal approach for Robben.
Kenyon said: 'We are aware of comments regarding Arjen made by Ramon Calderon, the new president of Real Madrid, since his successful election. The Arjen Robben situation could not be any clearer.
'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 Roman Abramovich, about Arjen's future.
'Any indication that a transfer is possible is completely untrue. We will not be entertaining any offers for Arjen, he is not for sale.
'Moreover, we note that Mr Calderon confirms that Real Madrid have spoken to Arjen. As a result of these various comments Chelsea will be writing to FIFA to ask them to investigate an illegal approach for our player by Real Madrid.'
