Manchester United welcome Arsenal to Old Trafford in the Premier League on Sunday.
United drew 1-1 with Real Sociedad in the Europa League on Thursday night, but they returned to Manchester ultimately feeling disappointed they didn't win the game in San Sebastian.
Ruben Amorim's side have often reserve their best performances for fixtures away from home during his tenure and they must deliver a strong display against Arsenal this weekend.
Arsenal head into this clash after an emphatic 7-1 victory over PSV in the Champions League and they are looking to win five successive games against United in the Premier League.
So here are five things to look for at Old Trafford...
Obi against his former club
Chido Obi wasn't involved in the FA Youth Cup quarter-final against Arsenal last weekend, but he might get the chance to play his former club in the Premier League on Sunday afternoon.
"THANK YOU SO MUCH," commented Obi under a picture of a teammate after the Under-18s knocked out Arsenal of the prestigious academy competition, which suggested there is no love lost between Obi and the Gunners.
Obi will relish the prospect of scoring against Arsenal at Old Trafford, although it would be a surprise to see Amorim include the youngster in the starting team, despite having eyes on the second leg against Real Sociedad in the Europa League.
Nonetheless, Obi could get another opportunity to show what he can do from the bench and he would love nothing more than to score against the club who he chose to leave last summer.
Obi has made an impact from the bench.
Rotation from Amorim?
Amorim's squad has been depleted by injuries and, speaking after the Sociedad game, he said United would have to physically "survive" against Arsenal to make it unscathed to next week.
Toby Collyer was introduced in the final mates in Spain and perhaps the youngster will be given a start against Arsenal. He returned to training on Wednesday after recovering from a small muscle injury and he proved he's got value to add before his momentum was disrupted by that issue.
The 21-year-old made an excellent cameo from the bench in the FA Cup third round victory against Arsenal in January and excelled against Southampton. Collyer was also given minutes against Brighton and followed those appearances with a start against Rangers in the Europa League.
After facing Rangers, Collyer said he was "hoping" for more starts in the remainder of the season and his ability to cover every blade of grass on the pitch means he'd be a logical selection.
Arsenal could create history
Arsenal won 2-0 in this fixture at the Emirates in December, which stretched their league winning run against United to four matches. That is Arsenal's longest winning streak against United in their topflight history and they are looking to extend that by winning at Old Trafford on Sunday.
If Arsenal win, they will become the first team in Premier League history to beat United five times in a row in the competition and that nugget of history will be added motivation for the Gunners.
Amorim said this United side is "maybe" the worst in the club's history and they will be responsible for another unwanted record if they suffer a defeat against Arsenal this weekend.

De Ligt improvement
Matthijs de Ligt had his best game since signing for United against Fulham and he followed that performance with another strong display against Sociedad in the Europa League.
De Ligt's performances have been a mixed bag and some fans have questioned whether he should have been signed, but he's starting to find his feet and look more like a United player.
You should always give a new signing a full season before making a concrete judgement. The Dutchman's improved form hasn't gone unnoticed and hopefully it continues for the remainder of the campaign.
Garnacho on the right?
Alejandro Garnacho and Joshua Zirkzee swapped sides against Sociedad. Garnacho has always played on the left and it felt strange to see him popping up in dangerous positions on the right.
United haven't score enough goals this season and nobody can blame Amorim for trying something new. Obi is currently the only other attacking option on the bench and Amorim attempted to move his chest pieces around the board by asking Zirkzee and Garnacho to be fluid.
It will be interesting to see whether the pair exchange sides again versus Arsenal because the inexperienced Myles Lewis-Skelly plays at left-back and he feels like someone Garnacho could target with his pace. Lewis-Skelly has been hot-headed in matches and Garnacho could get him booked.
