Chelsea are close to signing Real Madrid forward Robinho, according to Blues chief executive Peter Kenyon."Everybody expected negotiations to go close to the wire and that's what it will do but we're confident it will happen," he told BBC London 94.9."There are no hitches it's just a lengthy process."Reports have suggested that the 24-year-old Brazil international, who is contracted to Real until 2010, could cost the Blues about £30m. Kenyon added that AC Milan forward Kaka, who the Blues have also been linked with, would not be joining his compatriot Robinho at Stamford Bridge."Everybody identifies Kaka as one of the world's best players," said the Chelsea chief executive."All I can say it's flattering to be associated with the player, but there won't be anything happening this window or this season."He added: "Our manager Luis Felipe Scolari identified a couple of players he wanted, one was Deco, and we've seen the impact he has made, and the other was Robinho."It's important we supported Luis."Source: BBC
