If Amorim manages to get good new players to join the team, that's great. Hopefully, it can have a positive impact on United's game and development. It's just that advancing to the position to qualify for the Europa League next season seems too difficult.
A good coach can work well with available players and Sir. Alex Ferguson is a coach like this. With his management, Manchester United can use many normal players so well in their squad and combine them to make a winning team. Amorim actually needs some players to fit with his philosophy and tactics but he has to adapt well with players he has too.
Requiring to buy new players is common request from new coaches, but it does not lead to success if they are not capable coaches. We saw it in Manchester United with Solskajer, Ten Hag, Van Gaal as latest failed coaches in the club.
This season, not only United is seen to be experiencing a difficult situation. Tottenham and Man City are also experiencing problems with declining performance, like United.
They're in a truly hard situation but they will not want to be disqualified for UEFA league next season like Conference League or Europa League. They will try best to get a ticket to either Conference League or Europa League.
