Jose Mourinho has so far refused to put a timescale on Pogba's return but has admitted the midfielder is considered a "long-term" absentee along with Zlatan Ibrahimovic and Marcos Rojo.
Sources have told Sportnow that France manager Didier Deschamps is not expecting the 24-year-old, who has been in Miami, to be available before the next international break which begins on Nov. 6 -- the day after United meet Chelsea at Stamford Bridge. Pogba has missed five games since he was forced off after 19 minutes of the 3-0 win over Basel in the Champions League on Sept. 12 and will also miss United's Premier League clash with Liverpool at Anfield on Saturday.
Mourinho is also set to be without Marouane Fellaini, who sustained a knee injury playing for Belgium. The midfielder was substituted during the first half of their 4-3 win over Bosnia and Herzegovina after suffering strained knee ligaments.
After flying back to Manchester on Monday, he was assessed at Carrington on Tuesday. Belgian FA doctors expect the midfielder to miss two to three weeks. "No blow, no problem," Mourinho told Sky Sports.
"We don't cry with injuries, we may cry with the process that leads to injures, but we don't cry. We just trust the players that are going to help."
Romelu Lukaku is expected to be fit to face Liverpool after playing the final 23 minutes of Belgium's World Cup qualifier with Cyprus on Tuesday.
The striker missed the game against Bosnia with an ankle injury he suffered in training before United's 4-0 win over Crystal Palace ahead of the international break.
