Roberto Carlos has claimed Chelsea are interested in signing him.

The 33-year-old Real Madrid left-back has just one year left on his contract at the Bernabeu.

The Brazil international insists it would be a wrench to leave the Spanish giants but with elections for a new president due to be held at the beginning of July, he admits his future at the club is up in the air.

"Nothing has been signed although I have been told Chelsea want me," he told Spanish daily Marca. "I have told them they have to speak with Real Madrid, that there are a period of elections and that I have contract.

"I do not know what is going to happen in the elections and I have to know if the new president and the new coach want me.

"It is true there has been something from Chelsea and if it is concrete, it would give me a lot of grief to leave Madrid after so many years."

Chelsea have previously inquired about the Brazilian and reports in Spain claim Asier Del Horno could move the opposite way in a swap deal.
