They have locked in the title in the Bundesliga, so you can be sure they will focus on chasing the Europa League title this season. The challenge that is close to them is the match against AS Roma, AS Roma themselves have performed well in the Europa League so far, they were able to get rid of AC Milan who are actually better on paper than them, but they managed to win in 2 legs at once.
Opportunities are very open for Leverkusen, but they must focus on their closest match against AS Roma. In the European League, AS Roma is a team that can surprise. When many people doubted them, they were able to show their best, and last season they appeared in the final match, even though in the end they lost.
Even though there are 4 matches remaining, Leverkusen are certain to be champions of the Bundesliga, their points are no longer possible for Bayern to catch up, what makes me a little surprised is that VfB and Bayern have the same points, it would be very embarrassing if Bayern were shifted to 3rd place.
Leverkusen's current focus is the European League, their opponent is actually a team that is not very stable, because De Rossi has not shown that Roma has changed drastically, in contrast to Alonso, he has succeeded in making Leverkusen an unbeatable team this season in all competitions. Leverkusen's chances of getting into the final are much wider than Roma's.
