Manchester United is doing a good thing because it has been seen since last season that the defense is their team's weakness and now they are trying to cover this weakness.
Manchester United is a team that continues to improve for the next season, that is a positive thing and the transfer market is still long, making it more likely that Manchester United will improve their team, if they continue to make changes to their squad, I am quite optimistic that Manchester United could be better next season.
Everyone will also see how Manchester United will perform at the start of next season until the end of next season. Because from what I see, it is not only the defense line that Manchester United needs to improve, but the midfield and attack line also need attention from Manchester United. Because a strong team must be able to excel in all areas in order to win the Premier League and the European League, because Manchester United will also play in the UEL next season.
United's problem last season was so complex, the whole team needs to be improved, not only by having new players but strategy, mentality, and teamwork need to be improved alot.
Will they become better next season? I will not expect too much because even if they are improving their squad by getting new players I'm sure there is no instant effects.
If I have to predict. they will be still struggling hard next season just to be back on top 4 at the end of the next season.
They can get less loses next season compared to last season will be more than enough if you ask me, but of course I want to see them to be more competitive to make the whole league become more interesting to follow.
