Mourinho is keen on uniting with the Serbian midfielder at the Old Trafford, the Portuguese Manager re-signed Matic to Stamford Bridge in 2014 and together they won the league on Mourinho second spell at Chelsea.
Matic displayed a brilliant form last season under Conte he was paired with N’Golo Kante in the heart of the midfield, he helped Chelsea clinch the League title and also got to the final of the FA Cup.
Chelsea is ready to transact business with the Old Trafford outfit only if they are ready to meet up with the current valuation of the player.
The Blues will be looking for a fee around £40m ($51.9m) from United for their star player. It is believed that Manchester United will be willing to meet the Blues' asking price for Matic.
However, with Conte wanting to sign a replacement for Matic before allowing him to leave could make it complicated for United.
Manchester United have already secured the services of Victor Lindelof, who arrived at Old Trafford from Benfica.
According to The Guardian reported that Matic is set to become the Red Devils' latest summer signing but now remain to be seen whether Chelsea will be looking to bring in a second midfielder this summer or allow the Serbian to join Mourinho's side following Bakayoko's imminent arrival.
