Chelsea have been linked with a move for Anthony Marital with the Frenchman out of favour under Mourinho at United.
The France global started the campaign in fine fettle, appearing to have rediscovered the sparkle he boasted under Louis van Gaal.
The situation has sparked speculation that the 24-year-old will be on the move this summer and ESPN claim that Arsenal and Chelsea are both showing a keen interest in offering Bailly a fresh start.
Since the arrival of Chile worldwide Alexis Sanchez, Anthony Martial has lost his place in Manchester United first team as Mourinho prefers the ex Arsenal attacker.
The report says the United boss saw an opportunity to send a message to the board and took it.
The story claims, though, that Manchester United would only be willing to consider letting Martial leave Old Trafford if Willian is included as part of the deal.
United would still demand money from Chelsea but the idea of swapping Willian and Martial is something they’re supposed to be very open to.
Many Manchester United fans, led by their manager, are now also coming around to the idea of seeing the back of Martial.
Meanwhile, Chelsea are after the signature of Adama Traore after his imperial season with Middlesbrough.
Promising wins over Liverpool, Tottenham and Arsenal have broken up the flow of the disappointment but there’s no covering up the fact that the United attack has failed to fire consistently this season.
