Man Utd transfer news: How starting XI may look after January window
The Portuguese boss was given the chop following the Red Devils’ worst-ever start to a Premier League season.
United currently sit sixth in the table and trail leaders Liverpool by a huge 19 points after 17 matches.
Mourinho’s relationship with star signing Paul Pogba deteriorated rapidly over the course of the season while he fell out with executive vice-chairman Ed Woodward due to a lack of summer transfer activity.
United have already been linked with a host of potential targets for next month, including Juventus winger Douglas Costa.
The Brazilian enjoyed a fantastic debut season at the Allianz Stadium, on loan from Bayern Munich, but has found game time limited this campaign due to the arrival of Cristiano Ronaldo.
Meanwhile, a new central defender is a top priority for the Red Devils with their leaky rearguard having already conceded more goals than it did during the whole of 2017/18.
Both Toby Alderweireld and Kalidou Koulibaly have been linked with moves to Old Trafford, although United failed with a £40million bid for the Spurs star in the summer.
Napoli president Aurelio De Laurentiis has claimed United have also made a £95m bid for the Senegalese defender as the Red Devils desperately search for reinforcements.
Young defenders Ozan Kabak and Eder Militao have also been linked, although neither are likely to come straight into the starting XI if signed.
Elsewhere, Paul Pogba is expected to come back into the frame having been benched for the past three matches under Mourinho while Marcus Rashford and Anthony Martial will hope to nail down starting spots.
