Kaka could be on his way to the Emirates Reuters

According to reports in Spain, Real Madrid have approached Chelsea amid conjecture Jose Mourinho is endeavouring to sell Kaka next month.

Spanish publication El Confidencial claim Chelsea have been approached in regards to the aforementioned Brazilian international, in the hope that the west London Premier League club may be interested in taking the increasingly marginalised midfielder to Stamford Bridge next month.

Chelsea, along with PSG and AC Milan, have been credited as suitors in the past, and El Confidencial intimate all three are being encouraged to make bids for the 29-year-old, who moved to the Bernabeu in June 2009 for €68.5 million.

The former world and European player of the year has been in steady decline for the last 18-months and has never hit the same heights of his scintillating AC Milan career. Chelsea continue to be linked with a host of high-profile names ahead of the winter transfer window, and although Andre Villas-Boas has commented on a number of players, such as Gary Cahill, Luka Modric and Jack Rodwell, the mercurial Real Madrid star is not one of them.

While Real Madrid are reportedly willing to take a huge loss on the second most expensive signing in football history, the La Liga giants feel Chelsea, PSG and AC Milan would all be willing to match the former Sao Paulo prodigy's still lofty personal terms.

While certain sections of the Spanish media suggest Chelsea are being explored as a possible option, Villas-Boas recently suggested he was not looking to address his midfield, even though Kaka is perhaps more likely to play in a more advanced role.

"In midfield, we don't need players. Rodwell has been playing there this season. Midfield is not a sector where we're desperate to strengthen our squad. So at the moment those stories are false." The Chelsea manager said on Wednesday when pressed on some of the Blues' rumoured transfer targets.
