At least, Amorim only needs to guarantee that Manchester United can qualify for the next round. Because of course, the real competition will occur in the knockout phase later, so before they qualify for the next round, they must also really succeed in creating good chemistry and performance improvements at this time. Because after all, being at the top of the standings in this phase still does not guarantee that the team will be able to qualify for the final match later. Therefore, the most important thing is to be able to ensure that the team will still qualify by finishing in the top eight or maybe just in the top 24.
Man United is very likely to go to play-offs round. They need to win in the play-offs round if they want to continue to the next round. However, I'm sure Man United is capable to qualify for the knock-out phase because Man United looks stronger under Amorim's management. I think people expect more on Man United, at least they can reach semi-final round. So, Man United must focus on every match, every single match is real competition. Winning in every single match will improve the players' mentality. It is important because keeping the players' mentality is one of the keys for the success in this competition.
