Ole Gunnar Solskjaer has confirmed Paul Pogba has suffered another injury that will keep him sidelined for a "few weeks".
Pogba has only played seven times for United this season, with two cameo appearances coming over the festive period.
But he was left out of the squad to face Burnley on December 28 and once again for the loss to Arsenal on New Year's Day.
When asked before the Emirates meeting about why Pogba was not on the teamsheet, Solskjaer said: "He's injured.
"He's feeling some discomfort in his ankle and he'll be out for a few weeks, definitely."
