Chelsea face competition from Paris Saint-Germain in the race to sign Kaka, according to reports.
The Brazilian superstar has been heavily linked with a move away from Real Madrid in recent weeks after falling out of favour at the Santiago Bernabeu, with publication El Confidencial claiming his half-time substitution in the Copa del Rey on Tuesday night left the 29-year-old 'dejected' in the capital.
His withdrawal in the 3-2 victory is the latest line in incident which suggest his time may be up under Jose Mourinho, and talkSPORT claims newly-appointed PSG boss Carlo Ancelotti is keen to take the player to France.
The former Chelsea chief got the best out of Kaka during their time together with AC Milan, and will be hoping for similar results in Ligue 1 if he can persuade the player to make a January move.
However, the Blues are known to have a long-standing interest in Kaka, with the same radio station claiming Chelsea owner Roman Abramovich is an admirer of the former São Paulo starlet.
Despite playing only a bit-part role under 'the special one', another former Chelsea boss, it's unclear if Mourinho will be willing to let the player leave for a significantly lower fee than the reported £63 million paid to bring the player from the San Siro in 2009.
Were Andre Villas-Boas able to lure the player to Chelsea, Kaka would join compatriots David Luiz and Ramires in the ranks, whilst defender Alex is set to leave west London later in the month.
