The Frenchman left Old Trafford on crutches following the comfortable win, having headed down the tunnel for treatment after just 19 minutes.
It’s a major blow for Man United and José Mourinho, with Pogba expected to miss at least a month in which the Reds have some key games.
The 24-year-old will also miss two World Cup qualifiers for France in early October. The earliest he’ll be back will be United’s major clash with Liverpool on October 14th.
He had scans on Wednesday and United boss Mourinho will confirm the severity of the injury on Friday ahead of the team’s game against Everton at Old Trafford on Sunday afternoon.
As well as Everton, Pogba will miss games against Southampton, Crystal Palace, Burton Albion and CSKA Moscow. The Liverpool game in mid-October may also come too early for Pogba to be fully fit.
After a superb start to the season, with two goals and two assists in four Premier League games, Pogba had been handed the captain’s armband on Tuesday night.
His performances have cemented his status as one of the league’s best players, and for any side challenging for the title to lose their best player is an enormous blow.
None of those options have the same range of abilities or level of ability as the Frenchman, and there is no doubt that United will heavily miss him.
Pogba took to social media to respond to the reports, telling Instagram followers that “all will be fine”.
