Seriously, I don't think there will be a team in the Bundesliga that will be a challenge for Bayern Leverkusen. They are topping the table there, and I believe they are the favorites there. For now, Bayern Leverkusen have a high chance of winning the Bundesliga title. They don't have many obstacles there again, so even if they decide to focus on the Europa League, they can still make it in the Bundesliga. They are 10 points ahead of many teams, which is not a small interval, so you are right by saying they can do something here and make the Bundesliga title this season, and the fact that the Bundesliga title is already for them because I think there will be a team in the Bundesliga.
That's what you're thinking, but for me, I will say not that they're not a team that can challenge the Bayern Leverkusen, they are topping the table with a high point that doesn't make them proud to be their only favorite team in the Bundesliga, and I have doubt that they will not continue to remain in that top standing. Because there are also some teams that, even though Bayern Leverkusen meets with them, they can definitely find the match so difficult, team like West Ham, although they are also among the favorites in the Bundesliga.
However, You stated that Bayern Leverkusen is ahead of many teams with 10 points. I think you should go back to the table and cross-check again, because in my view, that's not what the table gave me. Bayern Leverkusen is only ahead of some teams with a few points, which is not up to 10 point.
