You are right that the Europa League final is no longer about who is the best in the Premier League and although both teams lost their last Premier League games, this says nothing in the context of the competition in the final. I am concerned about Manchester United’s attack and defence as this is an issue that Amorim has not fully resolved and even though the Manchester United striker has not shown his best qualities at all. If one of them can control the momentum to create chances then one of them will succeed and an early goal can also change the game.
I have said this before that the Europa league final will be somehow boring judging from the way both teams play at the moment. It's hard to say which team is better and which team is the worst among Manchester united and Tottenham. The way both teams qualify for the final is miraculous because their performance is never convincing as finalist in the second most competitive league in Europe after the champions league.
I can't predict accurately which team to win among them though but I still think Manchester United stand higher chance than Tottenham even with their poor performance. If Manchester United is said to be bad, then Tottenham will be the worst but you know the irony of football, anything is capable of happening.
