This season will provide Ruben Amorin a good opportunity to prove his skills, it will be interesting to see how far he can take a team that finished 15th last season. In preseason matches, United had good time against West Ham and Bournemouth but played a draw against Everton. We know that in EPL the competition is at its peak and team has to perform exceptionally well in all games to finish among top teams. Although United has good preseason but their real strength will be seen in upcoming season.
The fact that Manchester United finished the season so poorly is also Amorim's fault, because he prioritized only the Europa League games, and he openly ignored the rest of the games. In the new season, I only hope that the team's attitude to the Premier League will be more responsible, but they do not have another more important tournament, so they will try as best they can. Pre-season games are not an indicator, because their opponents may not play at full strength, may make a lot of substitutions and so on.
I think you shouldn't blame Ruben Amorim for being so serious in the UEFA Europa League because it was too obvious Manchester United couldn't make it to the top 5 in the Premier League table, and for Manchester United to qualify for the UEFA Champions League, Ruben Amorim decided to be more serious in the UEFA Europa League than in the Premier League if he could win the UEFA Europa League trophy and book a ticket in the UEFA Champions League, but he couldn't achieve his plan because Manchester United failed to beat Tottenham Hotspur in the UEFA Europa League final.
