Since I don't see much change in performance, I think Manchester United will have to play in Europa League next season too.
I'm afraid getting a ticket to the Europa League next season will be quite difficult for United considering their performance in the Premier League. If Amorim wants to build his own squad, then we will see some players leave United first and some will be brought in. The situation is unlikely to happen in a short time. Amorim will do it gradually and adjust the club's finances. Maybe United will not easily burn their money like they have done in the past.
The only way for them to be able to play in the UCL next season is to become UEL champions this season, because if they hope for UCL tickets through the domestic league zone it obviously looks impossible for them to get it, while if they also fail get UCL tickets next season via UEL path, there is actually still a way for their to play in European competitions next season, mainly in UEL from the path of FA champions like ten hag did Last season, but even so I think for now Amorim should be able to maximize their players to be able to achieve one of the opportunities that are still open, because to expect big changes with a total overhaul of the team will certainly not happen in the near time this is due to the transfer market that will close soon.
