The France international didn’t feature in Manchester United’s 1-0 loss to Newcastle United at St James’ Park on Sunday due to injury.
Ole Gunnar Solskjaer started with Fred and Scott McTominay in holding roles as Matty Longstaff netted a second-half winner for the hosts.
Pogba hasn’t featured for the Red Devils since a 1-1 draw with Arsenal at Old Trafford last week.
Even when the World Cup winner has been fit enough to play in Solskjaer’s team, his performances have been criticised.
Pogba was linked with a move away from Old Trafford in the summer to trigger further speculation about his long-term future at Manchester United.
Former Arsenal manager Wenger explained why Pogba is causing a number of problems at Manchester United this season.
“First of all, I think Paul Pogba, since the start of the season, has never been completely fit injury-wise,” Wenger told beIN Sports.
“He doesn’t look, I’ve seen him the other night against Arsenal, he doesn’t look completely confident physically and he’s the type of player who has a huge physical power.
“He needs to be perfectly fit physically. ‘After that, when a player wants to leave and you stop him from leaving, you know you go through a process of rebuilding the relationship that the first thing that suffers is the performances.”
Manchester United signed Pogba in an £89m deal from Serie A giants Juventus in the 2016 summer transfer window.
The French midfielder has only won the Europa League and the League Cup at Manchester United.
Pogba has been unable to revive the Red Devils’ ailing fortunes despite his sizeable transfer fee.
Manchester United will take on their bitter rivals Liverpool FC in their next league fixture on Sunday 20 October.
