Amorim has no chance to get the Champions League through the Europa League because Manchester United are too weak to do it. Moreover, I think Amorim should focus on the Premier League because they are doing so badly there that if Manchester United continue to lose, Amorim could lose their place much faster than it was initially expected. I don’t think it’s wise to spend energy on the Europa League when they are only 7 points away from the relegation zone in the Premier League.
Judging by Manchester United current former, this can be very much acceptable but judging from football perceptions of the fact that anything can actually happen at almost anytime is another thing that we me need to put in to consideration, you may wo der what I mean by this and this will be s typical example, last season in the europa, we had bigger teams like Liverpool and the least expected team won the title so who knows such could be with the cas of Manchester United this season in the europa and of course if they do, it's an automatic ticket to the UCL. So Manchester United could prioritise the Europa and cease that opportunity to create better ones for themselves.
My ideas cannot be matched with that of the coach, but i suggest Amorim to prioritize one league he is into, you can't be performing badly with tight escapes from several important fixtures and expect a deserving outcome at the end. United can focus mainly in the Europa League, not mean they won't try their best in the Premier League but United are too big to go under relegation, at worst they would end this season from 12th position upwards if they still continue to lessen in form or fail to make progress.
