The club is reportedly still considering Mourinho's position after it was claimed he had fallen out with multiple players inside the dressing room.
Although the emphatic 3-2 comeback win over Newcastle United on Saturday has taken some pressure off the Portuguese, United's board are still reportedly meeting this week to discuss his future.
With Mourinho's job under severe scrutiny, it does not look like finding a replacement will be an easy task.
Zinedine Zidane has been tipped as a favourite to take over if the 55-year-old gets sacked, but the Frenchman's agent recently suggested that he has no interest in coaching in England, and wants to complete his one-year sabbatical from the game
Several names, including former Chelsea boss Antonio Conte and Tottenham Hotspur coach Mauricio Pochettino, have been linked with the job, but a new report by the Daily Express has thrown Wenger's name into the mix.
The Frenchman, one of Mourinho's biggest arch-rivals ever, is currently without a club, and it is believed his attack-minded football philosophy would appease the United board.
In addition, Roberto Martinez has also been linked with the Red Devils. The former Everton coach has received a lot of credit after guiding Belgium to third place at the 2018 FIFA World Cup, but it is uncertain whether or not he would be prepared to give up his role with the national team.
