This match will determine who will secure first position, Bayer Leverkusen can increase its lead to five points if it manages to beat Bayern Munich. On the other hand, if Bayern Munich wins, there will be a change in position at the top of the standings. This match is very crucial for both teams, Bayern Munich really wants to regain control of the standings, while Bayer Leverkusen wants to maintain a positive trend as the only unbeaten team in the Bundesliga.
Leverkusen really benefited in this game because they acted as hosts. The draw they achieved against Borussia Moenchengladbach must be used as evaluation material to show another impressive performance in this big match.
This will be a big match in Week 21 and both teams want to maintain a positive trend even though Bayern Munich previously lost to a mid-table team. Leverkusen are also aiming to set a single-season unbeaten record and Alonso will definitely be looking for a way to keep Bayern Munich at bay. A draw might be much more possible for Bayern Munich because the match will take place at Leverkusen's home ground so the enthusiasm for winning will be much greater and they also have the advantage of playing in front of their own crowd.
I predict that Leverkusen will win the match with a narrow score because so far the game they showed at home to Bayern Munich in the first leg managed to hold them to a draw. Now whoever comes out on top in the match will be at the top of the standings and that means Leverkusen cannot waste this opportunity.
