Even without Höjlund, Manchester United will win this match. I mean, if they want to be in the top four, they have to win. In recent games, even if they concede goals, they score a lot of goals and win. That's why defensive mistakes are not a big problem.
I think Aston Villa will also win, so the points difference will not decrease. Nottingham Forest cannot pose a serious threat. The team that has lost 3 games in a row at Villa Park wouldn't allow the 4th one to happen. Also Watkins is in great shape.
Aston Villa is already winning their match, but in the match between Manchester United and Fulham, everything is not so good for the hosts, in the 18th minute of the match, only the guests attack. I don't know, despite Manchester United's very good performance in the last five matches, I'm still very skeptical about this team. I’m not sure that they will be able to finish the season in the top 4, despite the fact that they came quite close, there are still teams higher up that will be quite difficult to beat, and of course if they can continue to win they will be able to achieve this, but I doubt it.
