Arsenal, on the other hand, will leapfrog United and move into fourth should they defeat the Red Devils for the first time since May 2017.
By contrast, the visit of Solskjaer's men is Arsenal's last against top six opposition. I think we need a new contract there.
That suggests Emery could make major changes from the side that lost 3-1 to Rennes in the Europa League on Thursday.
"Not a good experience today, because we couldn't do our work in hard moments, in hard minutes, with one less player, like we wanted".
Arsenal goalkeeper Petr Cech, however, is confident they can still progress to the last eight of the competition.
But things began to turn sour for Arsenal afterward.
"We're going to try and pick ourselves back up".
Alexandre Lacazette raced into the box and went to ground under small contact from Fred, allowing Aubameyang to redeem himself for his North London derby penalty miss by tucking this latest one past De Gea down the middle. "I am finding the best decisions for the team", said the former PSG coach.
Romelu Lukaku has had a rough time at the start of the season.
"Honestly, it was our goal - we were working towards it each day".
In sharp contrast to the first half, it was United who were fast out of the blocks at the restart, Lukaku rolled in by Rashford only to see his shot turned behind by the outstretched leg of Leno.
"They might form a very nice partnership together, because I wouldn't like to be a defender having them two running at me!"
"Henrikh played well there, so credit to him because it's not his natural position but he's done very well for the team", said Cech.
