Erik ten Hag insists he is taking things one game at a time, but he might need to look ahead to the weekend when he considers his lineup against Crystal Palace tonight.
United head into the match at Selhurst Park buoyed by a derby win over Man City and know another positive result is crucial ahead of their trip to face Arsenal this weekend. The temptation for United to stick with the same lineup that performed so well last time out is strong, but doing so is not always the best option.
In particular, Ten Hag has two midfield dilemmas he needs to solve if he is to give his side the best chance of securing victories in both of their away matches this week.

The first comes with regard to Casemiro, who is just one booking away from a suspension. The 30-year-old is crucial to everything United have done as of late under Ten Hag, so it might make the most sense to rest him in midweek and keep him fresh for the clash against Arsenal.
United's issue is that they look a much weaker side without the Brazilian, and dropping him tonight could well see them lose momentum ahead of their trip to the Emirates.
The other dilemma is what to do with Fred. He was a standout performer in the derby day win and is another player just one booking away from a possible suspension.
While he might not be as technically gifted as his compatriot, his role last weekend was arguably more important than Casemiro's. After a shaky start, he grew into his combative role and was crucial in nullifying the threat of Kevin de Bruyne with his tight man-marking.
Fred is the ideal big-game player given his work rate and tenacity, a role he should reprise against Arsenal, though he has often looked out of his depth in matches where the onus has been on United to attack.
Given that the duo are both so integral to United's approach against the bigger sides in the league, it makes sense to rest them both against Palace, but there is not much scope to do that.
There is an argument that Fred might be more integral to United's chances of getting a result against Arsenal this weekend, but Casemiro is quite clearly the better player and one with vast big-game experience.
In that case, it makes more sense to start Fred at Selhurst Park, though doing so would rely on him adopting the deeper midfield role, which is not something he is an expert in and could leave him vulnerable to picking up another booking.
It doesn't seem like there is a right or wrong answer with regard to Ten Hag's midfield selection tonight, and as long as United win, then the decision will be vindicated regardless.
But with an even bigger game on the horizon, resting anyone tonight would only confirm just how integral their role is for the games that really matter.
