Manchester United are monitoring the situation of Cesc Fabregas at Chelsea, according to a report in the Daily Mirror, and could move for him if he is deemed surplus to requirements by their incoming manager Antonio Conte.
Mourinho signed Fabregas in 2014 for Chelsea and is said to still have a good relationship with the man recently appointed as manager at Old Trafford.
The Mirror's article describes the Spaniard as 'a favourite' of Mourinho, although last season did not see Fabregas perform to his best in a side that finished 10th in the Premier League as the Blues put up a dismal defence of their Premier League title.
Fabregas played his part in Chelsea's title success in 2015 when he provided 19 assists across the course of the league campaign as the side lifted the title under Mourinho.
If any kind of move materialises, it will be because Conte has decided to overhaul the midfield at Chelsea but he is joining his club perhaps later than desired given he presided over Italy's run to the quarter-finals of Euro 2016.
It looks as though there could be a flurry of activity at the club now Conte has arrived at Stamford Bridge, but there seems to be a degree of uncertainty from United that Fabregas will be available.
Undoubtedly, there is quality there that can add some creativity and intelligence to any side, and it will be interesting to see just how this story pans out.
