Chelsea keen on Robinho says his agent

(CNN) -- Chelsea are interested in signing Real Madrid winger Robinho, according to the Brazilian's agent Vagner Ribeiro, who told Spanish Sports daily AS that he had spoken to Chelsea sporting director Frank Arnesen.

"It's true that Chelsea are interested in signing Robinho," Ribeiro told AS.

"They have been after him for a while and there has been much more contact since Scolari became the new Chelsea coach.

"I met with Arnesen in London and he confirmed to me that Chelsea wanted my player for next season."

There have been reports that Real would like to offload Robinho to set up the signing of Manchester United's Cristiano Ronaldo and Ribeiro is not happy with that.

"Neither Robinho nor I like the fact that Real Madrid can use him as part exchange in their bid to sign Cristiano Ronaldo," he said.

"We don't like this attitude and we want Madrid to start valuing Robinho because at the moment they're not.

"Robinho is as good a player as Cristiano Ronaldo or better. The difference is that Cristiano Ronaldo reached the Champions League final and Robinho didn't.

"But if Robinho had won such a title he would be at the same level as Cristiano."

Robinho scored 11 goals in 32 games last season, his best since joining Real in 2005.

Ribeiro said that the 24-year-old was not anxious for a move but would consider it if Madrid continued to undervalue him.

"Robinho's priority is to continue at Real Madrid," he added. "But he cannot stay in a place in which they don't recognize his talent and at the moment Real Madrid are not doing that and I'm not talking about money.

"I'm referring to the fact that they are undervaluing him in comparison to Cristiano Ronaldo."

Chelsea, whose new Brazilian coach Luis Felipe Scolari took up his post on Tuesday, signed Barcelona's Deco on Monday.
