Reports claim Victor Moses is open to leaving Stamford Bridge in the January transfer window.
Moses is yet to start a game in the Premier League this season under Maurizio Sarri, despite winning the title under Antonio Conte in 2017.
And according to the bookies, Manchester United are the favourites to sign Moses, 27, in January.
Alex Apati of Ladbrokes said: “Moses has struggled for game time since Sarri’s Stamford Bridge arrival.
“Amazingly it looks as though former boss Jose Mourinho could make a shock move for the Nigerian.”
United are priced at 3/1 to sign Moses, while Crystal Palace are next in line at 10/3.
Palace are struggling for results and manager Roy Hodgson could be backed in January in order to boost his squad’s survival chances.
Everton, Wolves and Leicester are also in the running for the Nigeria star.
Mourinho worked with Moses during the Special One’s time at Stamford Bridge.
A lot has been made of Chelsea’s performances under Sarri this season.
The Blues currently sit third in the Premier League table, two points behind Manchester City and Liverpool.
