in the Europa League only against Feyenord, it must be difficult to qualify through a penalty shootout. aka escaping the luck factor when compared to leverkusen and liverpool, the level is still very far away. to win the Europa League is very difficult or you can say impossible, the luck factor might be able to bring As Roma champions.
It is still too early to talk about the luck factor in the Europa League this season because there are still many strong teams in the Europa League this season who may still be able to beat weak teams to become champions in the Europa League. For example, like the two teams you mentioned, Leverkusen and Liverpool will definitely dominate the European League this season to win the title with the abilities they each have at the moment.
If Leverkusen and Liverpool meet in the final, it will be the toughest match this season. Equations and statistics suggest that these two teams will face each other in the final, but if we look at the most competitive matches in the Europa League, it will be Liverpool and Leverkusen. If the performance in Bundesliga or English Premier League is considered then I would say Leverkusen is performing better than Liverpool. Bundesliga has tough opponents yet Leverkusen are not dropping points in any match but they are fighting back and gaining points. This team has enough fighting spirit and from that mentality I think Liverpool and Leverkusen will have a tough fight.
