This time they scored the goals that were needed to win the game, but usually Manchester United has a ton of problems to convert their chances into goals. It has been like that for a long time now, not only this season but last season was the same problem. You would think that they have a deadly attack when you read all the player names on paper, but problems seem to have been far more challenging than that. Anyway, everyone in the team probably knew that if they lose this one, they are literally in the midst of relegation competition.
The next game will be away from home against Crystal Palace and they could finally be able to start a small winning streak if they take that one home as well. Afterwards they are going to face Tottenham and that would lead them into the right direction if they are able to win that game at Old Trafford. It would definitely secure the job for Ten Hag for quite a while I suppose.
The win may give some optimism, but it was a win against a team that had yet to pick up a point, so the joy of the win should be tempered. It was good that Rashford scored and ended his goalless run, and it was also good that De Ligt felt more confident and showed the performance that ten Hag expected from him when he invited him to the team. But Manchester United will need to be assessed against stronger opponents, the upcoming matches with Crystal Palace and Tottenham will be quite suitable for this.
