Actually, the one who will be more under pressure for the match is the host, Dortmund, because Bayer Leverkusen will still try their best to win in the away match. Moreover, Leverkusen is currently only four points behind the top of the Bundesliga standings so Leverkusen will do their best to get full points at Dortmund's home. In addition, Dortmund this season has not been very consistent in winning matches so Leverkusen will take advantage of this when they come to Dortmund's home.
Dortmund have so far not found good form and consistency in the league, so it is not surprising that the match against leverkusen will be a difficult match for them despite playing at signa iduna park, I think the match later will be tight and will likely depend on the performance of key players from both teams, I think in the match later, dortmund will still rely on guirassy and juliant brandt to destroy the tight defence of leverkusen, but instead I see maybe leverkusen will be able to be more dominant with wirtz will be the difference in the match later, I personally tend to see if leverkusen will win the match and continue to stick tightly to munich at the top of the standings.
Dortmund is not really doing well in the Bundesliga, but they are trying and competing in other competitions. Leverkusen are in a great form now, they have come back to their winning stake, and their match against Dortmund can be a challenge games because Dortmund usually perform great when playing with a big club, and even the season that Xabi Alonso won the Bundesliga title, when they face Dortmund, they didn't get the opportunity to defeat them, they just drew the game home an away. so am sure still Dortmund will not make Leverkusen defeat them at home. so I believe they will do anything possible to achieve three point against leverkusen. And then they can come forward in the league table.
But I still believe Dortmund will give it their all, even if they are not in excellent form. They will not try to lose points at home. Dortmund has historically had the opportunity to defeat Leverkusen, but after the arrival of Xabi Alonso, they have improved significantly and are now winning matches and trophies. Let's see how this season ends and see if Xabi Alonso can win any awards this season.
