Amorim will have quite a lot of work in the MU team to bring them through to the next round of the Europa League. Although the chance to qualify is still open, I see competing with other teams will be quite difficult for MU even after qualifying.
Man United actually still has a chance to finish the league phase in the top 8. If Man United can win in the next 3 matches, the chance is still quite open. In the next 3 matches, Man United has quite easy opponents. So, I think it won't be so hard for Amorim to lead Man United to the next round. However, surely they need a little luck to qualify automatically.
Amorim cannot only focus on the Europa League, of course, he will be demanded to improve MU's position in the EPL standings. a big challenge, but many hope Amorim can do it. we will see how MU will shop in the transfer market later, maybe the results will help MU in the rest of this season.
I think the priority of Amorim is to improve Man United position in EPL table. Europa league is important but I seems EPL will be more important. Sure, all the fans expect Man United to get great results both in EPL and Europa league. But I think in Europa league, Man United is probably to reach the quarter final only. It will be difficult to reach semi-final and final round. There are many strong teams in Europa league this season.
