|Antonio Conte has used Fabregas more than any other midfielder this campaign|
According to Daily Sun, Mourinho is a big fan of 30-year-old Fabregas, and has been monitoring his situation since moving to Old Trafford.
He bought Nemanja Matic from Stamford Bridge over the summer and the Serb has played a key role in United's midfield.
But Stamford Bridge chiefs are reluctant to lose Fabregas after he impressed Antonio Conte.
After a difficult spell at the club, the ex-Arsenal playmaker has proved his class - especially when N'Golo Kante was sidelined.
Fabregas has 18 months left on his current deal and is chasing a two-year extension.
Chelsea have a policy of only offering 12-month contracts to players over 30 but Gary Cahill agreed four-year terms just before his 29th birthday.
Fabregas has started eight of 10 league matches and been on the field for more minutes than any of the club's other midfielders.
Conte is understood to have sat down with him over the summer after Tiemoue Bakayoko's arrival.
The Italian was keen to assure the 110-cap international that he had a role to play.
And after a strong start to the season and regular football, Mourinho may find it difficult to tempt him away. SHARE THIS STORY USING ANY OF THE BUTTON BELOW ⬇ PLACE YOUR TEXT ADVERT BELOW ⬇⬇⬇
