Liverpool and Leverkusen are the main candidates to win the title, meanwhile Milan, Atalanta, Roma, Villareal are teams that could also provide a surprise in the Europa League this season. We don't yet know which team will advance to the final, but considering the performance of each team in the domestic league, Liverpool and Leverkusen are two of the 16 best.
Personally, I tend to think Liverpool can advance to the final round of the Europa League this season, but other teams are simply not worth taking lightly. There will be 8 teams that will qualify for the quarter-finals and some of them are easy to predict. Leverkusen, Liverpool, Milan, Roma, Benfica, Atalanta, Villarreal and West Ham are my favorites for the quarter-finals, but of course there is no guarantee whether they will actually qualified.
They stand out domestically. In the Bundesliga, Leverkusen has dazzled, exceeding even Bayern Munich. For this season, they seem determined to win both their league and Europe. Since Liverpool dominates the Premier League, I agree that its hard to predict who will win the trophy.
Although Milan, Atalanta, and Roma are charming, I doubt they're consistent. Leverkusen and Liverpool seem at a different level. I agree with your quarter-finalists, but football is unpredictable. While Leverkusen and Liverpool look expected to dominate, the game's charm resides in its ability to surprise.
Leverkusen is also in the cup as well, which means that they could end up the season with three cups. Not the treble we are used to, we usually get treble winners to be UCL winners and not Europa winners, but it's possible. To be fair same goes for Liverpool as well, they are still in FA cup right?
Leverkusen could end up winning their league, which looks more than likely at this point and Bayern is not even close anymore and looks like it will be easy win for Leverkusen, Cup doesn't even have Bayern anymore, so Leverkusen really doesn't have any big opponents at all, and we are talking about Europa, which has Liverpool as their biggest rival, but aside from that not many other teams that can rival them at all.
