As revealed by Sportsmail, the self-styled Special One, along with fellow former Blues boss Guus Hiddink, are top of Chelsea's wishlist to replace the axed Carlo Ancelotti. Mourinho left Stamford Bridge after a bust-up with Roman Abramovich in 2007 but they have since patched things up, opening the way for Mourinho to make a popular return to West London.
Hiddink remains favourite to replace Ancelotti, who was dismissed at Goodison Park on Sunday night after a 1-0defeat by Everton, and looks an even better bet for the post after Mourinho hinted that he is already focusing on next season at the Bernabeu.
Making a point: Jose Mourinho addressed Real Madrid's fans with a message on the club's website
In a message of thanks to Madrid's fans that appeared on the club's website, Mourinho said: 'The season has finished and I want to thank the Real Madrid supporters for all the affection and support they have given to both the team and the coaching staff.
'We've worked seriously and with dedication, but obviously we leave to you the analysis the work this squad has done during this last year.
'We will return on July 11 with the same passion and with the same motivation as always to continue trying to dignify the prestige and the incomparable history of Real Madrid.'

Mourinho had not spoken to the media since being handed a five-match ban by UEFA for his actions during and after the fiery Champions League semi-final first leg against Barcelona at the Bernabeu last month.
That ill-tempered encounter also saw both Spanish rivals lodge complaints against the other to UEFA afterwards, with Barca singling out Mourinho for his controversial post-match comments and Madrid responding by accusing the Catalan club's players of 'feigning aggressions' during the clash.

Ahead of the second leg in Barcelona there were also allegations of racism against Barca midfielder Sergio Busquets towards Madrid defender Marcelo in the same game. UEFA ultimately dismissed those allegations of racism due to 'a lack of strong and convincing evidence', while European football's governing body also rejected Madrid's complaint about the supposed actions of Barca's players during the match.
Mourinho appeared to allude to those decisions in his message to supporters saying: 'Finally, I want to end with a very simple wish, which is that next season we recover certain principles that nobody should ever forget, and which this season some football professionals and some institutions have sometimes forgotten, and which must be the basis of our sport.

'To talk of fair-play, of respect to your opponents and of the red card to racism must not just be words, they must be facts.
'I repeat, I have the hope that next season we can recover for our sport these absolutely fundamental principles.'
This was Mourinho's first season in charge of Madrid, with whom he won the Copa del Rey with victory over Barca in the final and finished second to Guardiola's side in the Primera Division.
