The only thing that I love in the competition is that, it's unpredictable. A weak club with a poor performance in her domestic league might end up winning the trophy again this season. We have seen such happen times without number in the past. I don't have any favorite team, when the competition gets to the semifinals, the winner will be revealed.
Just like Sevilla, they were known as a weak club in the domestic league but consistently managed to win the UEFA Europa League.
I also remember Atalanta being seen as a weak club in the domestic league. Even in the Europa League, they were almost overlooked because everyone was focused on Bayer Leverkusen. But Atalanta surprisingly managed to win the Europa League title.
From this opinion, I completely agree with you that in the Europa League, it's difficult to predict who will win the title in the final.
