In addition to top pairs like Roma - Brighton, I would pay attention to the Sparta - Liverpool pair, despite the fact that Sparta will be a clear underdog it can cause a lot of problems for Liverpool (which is focused on the Premier League), their victory over Galatasaray impressed me.
Apart from having to focus on maintaining their position, they also need to maintain their performance in the Europa League. The potential for getting into the final is huge for these two teams based on their current performance, I really hope the Europa League final has an atmosphere like the Champions League final.
Previous years have taught us that underdogs are more likely to play in the finals than favorites, but I liked your idea. Taking into account the fact that Bayer's championship is already practically a fact (a truly historical event after 5 second places and the nickname Neverkusen), and Liverpool has good chances, there is a possibility that the champion of Germany will play against the champion of England in the Europa League final. Interesting story, isn't it?
But I don’t agree that everything else is not interesting, now it’s the playoffs and I like almost all the pairs, each of them has some meaning and interest.
