the match later will be very decisive for leverkusen who are ambitious to catch up with them from munich, although indeed facing dortmund is not an easy job, but I think with the consistency and performance possessed by leverkusen allows them to win 3 points at dortmund home later, especially in another match munchen will face gladbach which has often made it difficult for them, so it will indirectly motivate alonso squad to get win over dortmund in the match later.
Even though things are going well for Bayern, we can't deny that Xabi can make the difference. If he plays like they did last season, they can easily get to them, and this is what they should do to make the Bundesliga really good. Xabi has a team that has experience , they are Looking to stand out and why not look to win the UCL, but he has to put more love into the Bundesliga, I think they are concentrating much more on the UCL. Well, I understand them , Madrid does too The bad thing is that it is very difficult for them to recover in their local Leagues.
Each team will certainly divide their priorities and no one will ignore one of them between the Bundesliga and the Champion League competition, of course Leverkusen wants to focus on both, although in the Champion League the competition is fiercer which makes Xabi Alonso have a little difficulty.
In the Bundesliga, Leverkusen is currently behind Bayern Munich in points because Leverkusen's performance was a little bad at the beginning of the season, but now Xabi has slowly managed to improve it and now they have returned to their top performance.
Visiting Dortmund's headquarters is certainly not an easy job, especially since we know that this season Dortmund is quite strong when playing at home, even Bayern Munich was unable to win there, so I think it will be the same with Leverkusen, maybe they can only get 1 point, apart from that, the competition with Bayern will continue to be fierce, especially now the two are only 3 points apart.
