Real bullish over Carlos

They shouldn't use players like products and think they can do what they like with us Roberto Carlos

Real Madrid defender Roberto Carlos has confirmed Chelsea are interested in him - but the Spanish club remain confident of keeping the Brazilian.

"When news like this comes out into the open, it is because there is something in it," said the Brazilian.

But Real president Florentino Perez he would persuade World Cup winner Carlos to stay at the club.

"He has got a year left on his contract with Real Madrid and he is going to fulfil it," he said.

Spanish media have reported that the defender has been offered a four-year deal worth around £4m.

Perez added that Real had not yet made the player an official offer and criticised the defender for trying to use the media to bargain with the club.

"But Carlos has complained that the club are treating him as a commodity rather than a player.

"My record won't allow me to accept this sort of thing. I am not a product. When I go out to play I give everything," he said.

"(David) Beckham sells a lot, but he also earns a lot, just like Ronaldo and Zinedine Zidane.

"But they shouldn't use players like products and think they can do what they like with us."

Carlos joined Real in 1996 from Inter Milan and has won three league titles and three European Cups with the club.
