You are absolutely right and that is what often makes it difficult for some team to win the Premier League title, those team that failed to compete for the Premier League title only have potential in several other competitions but the main one is the Europa League considering that this is one of the League that is quite important but can still provide very big opportunity to win it easily.
If we talk about Manchester United, I actually only focus on them here, there is no hope for the Premier League and they could beat several team from other domestic leagues here to compete for the title, it would clearly be very satisfying assessment if Amorim managed to bring Manchester United to win the Europa League this season.
In the European competition I think Europa league is one of the most difficult one to win, I think it even more difficult to win than the champion league. The reason is that most team that participated in the champions league every year are teams that have won it before, the like of Liverpool, Real Madrid, Barcelona, inter Milan, and so on but in the Europa league most team that participate haven’t won, in recent years the team that win the Europa league are teams that fail to qualify from the champions league group stages, the likes of Sevilla, Manchester United too, Villarreal, Atletico Madrid, Chelsea and so on. So these teams now in the Europa league will put in every effort to win it. I think it still easy for Amorim to make the Top 6 in the English Premier League than winning the Europa League.
