Manchester United seems to have failed to utilize all their big signing players like Sancho, Anthony and Hojlund. Seeing this pattern, signing another attacking players won't give a better impact on their offense line. I really don't think this problem comes from the ability of the players. The management and Ten Hag himself need to find the cause of the problem before they prepare the plan for next season.
What the management of Manchester United and Ten Hag must improve for next season is to find players who are able to liven up their attack line very actively. So that Manchester United itself can see players who are really skilled at providing passes from midfield to attack so that there are slight changes that Manchester United can feel next season. Apart from that, Ten Hag himself must also be able to create better ways to train his players because at Manchester United there are already young players who need to get more attention.
They have weaknesses in almost all their lines, their defense doesn't work well, their midfield can't provide a good balance, and their front line appears inconsistent. They have to fix it completely without leaving a single gap that could become their weakness in the end. This season there are no more opportunities for them, all they can do is try to play as well as possible in the remaining matches.
They can focus on next season, where next season they can bring in new players who can help their overall performance. I also hope that they can quickly build chemistry between the players, because from what I see the relationship between the players is not very harmonious. Like it or not, good chemistry must be present in a club, because that will affect how they carry out the strategy given by the coach.
