Next season, Manchester United will still have a little difficulty getting super good results if they don't buy any young players to complement their weak lines.
Manchester United's performance wasn’t that good last season, even though they won the FA Cup, their performance was so poor in the Premier League because I never expected them to end the season in the position in which they ended it. Manchester United's poor performance was caused by some players who were injured, and I am sure they will be back before the season starts. Also, Manchester United should sign some new players. There are some players who are playing for the team like they are being forced to play for the team, players like that should just be allowed to join other teams or should be on the bench till they are ready to play well for the club.
Last season they finished the league in 8th place, which is a really bad result for them. They could not achieve a consistent winning streak throughout the season, I do not think the team could be very successful with their current squad. Of course, the Premier League is one of the most difficult leagues in the world, but I think that the place where a team like Manchester United should be should always be among the top 3 teams.
They need to make good transfers urgently, otherwise we will see a similar league performance next season
