Carlo Ancelotti is being lined up for a sensational return to Chelsea.
The Sun says the Italian is the champions' first choice to replace Antonio Conte whose future continues to be in doubt.
Chelsea chiefs do not expect Conte to see out the remaining 20 months of his contract and have already started planning for his exit.
Ancelotti is keen to resume his career in the Premier League after being sacked by Bayern Munich despite winning the Bundesliga in his first season in charge.
Despite his sacking, Ancelotti is on good terms with Chelsea owner Roman Abramovich and has kept in touch with Blues executives during his time at Real Madrid, Paris Saint-Germain and Bayern.
