Chelsea owner Roman Abramovich wants to sign Edinson Cavani over Atletico Madrid striker Diego Costa this summer - according to the author of a recent book about Jose Mourinho.
Diego Torres Romano's The Special One: The Dark Side of Jose Mourinho was published as a English translation earlier this year, and was well received by almost everyone except the Chelsea boss himself.
But Torres, who also writes for Spanish newspaper El Pais, often has the inside track when it comes to news around Mourinho.
And in the aftermath of Chelsea's 0-0 Champions League semi-final draw against Atletico Madrid on Tuesday night, Romano told Daily Telegraph journalist Henry Winter on Twitter that Chelsea owner Roman Abramovich doesn't want Costa.
He tweeted: @filippomricci @henrywinter Last news from Mendes's camp is that Abramovich said he wouldn't sign Costa. The russian wants Cavani."
The Atletico Madrid forward has been linked with Chelsea heavily since the January transfer window, with the club thought to be keen to strengthen its attacking options in the summer.
But Torres claims that Abramovich would prefer to sign Cavani this summer - not Costa.
The El Pais journalist says he's spoken to officials close to Jorge Mendes, the super agent who represents Mourinho as well as Diego Costa, and the word is that the Russian oligarch favours Cavani.
