Chelsea boss Carlo Ancelotti has admitted he would like to be reunited with Kaka, but has conceded a deal to sign him is unlikely.
The Italian managed Kaka while the pair were at AC Milan, before the Brazilian playmaker moved to Real Madrid in a 68.5 million euro (£57.5 million) deal last summer.
He had been heavily linked with a switch to England the previous January as Manchester City were rumoured to be close to bringing him to Manchester but the deal never materialised in the end.
Ancelotti said: “Kaka would do well for my cause and I have spoken with him on a regular basis.”
“But unfortunately he cannot come: firstly Real Madrid don't want to sell him, and secondly we would need a consent over the transfer, and thirdly it would be a multi-million operation. None of these conditions exist.”
The Italian also rubbished plans to sign another striker, despite ongoing rumours about a mega-bucks deal to bring Fernando Torres to Stamford Bridge.
Ancelotti said: “If you have someone like Didier Drogba who scores 37 goals then why should I look for another [striker]?”
One players the Blues could sign, though, is Portugal left-back Fabio Coentrao – if Ashley Cole makes the move to Madrid.
Cole looks certain to favour a move away from England and Chelsea have targeted the Benfica ace, who impressed at the recent World Cup.
Furthermore, Ancelotti admitted City will be one of the closest challengers for their Premier League crown after they have spent big, and he feels there will be more signings on the way.
“They spend plenty and Roberto Mancini is equipping a great squad. Wait and see, they will also sign [Aleksandar] Kolarov and [Edin] Dzeko,” he added.
