Bayern haven't beaten Leverkusen since 2022 and, as well as picking up a point in the league meeting at the Allianz Arena back in September, Alonso's men also dumped their title rivals out of the DFB-Pokal this season by beating them 1-0 in Bavaria in December. Furthermore, the last time Bayern travelled to the BayArena, in February of last year, they were completely dismantled in a chastening 3-0 defeat that pretty much ended their reign as champions of Germany.
Obviously, a lot has changed over the past year, but it's not as if Leverkusen have capitulated and Bayern have become infallible. Just look at the Champions League; while Bayern were in Glasgow for a play-off game on Wednesday, Leverkusen were enjoying a midweek off after progressing directly to the last 16 thanks to home wins over the likes of AC Milan and Inter.
In Florian Wirtz, Leverkusen are also arguably in possession of the best attacking midfielder in world football right now, while Alonso is spoiled for choice up top, with Victor Boniface returning from injury to compete for a starting spot with Patrik Schick, who has more Bundesliga goals from open play this season (14) than penalty king Kane (12).
Leverkusen clearly have to win. They know that anything other than three points would probably leave them with too much ground to make up, given the way in which Bayern are swatting aside nearly every other team in Germany. However, they don't seem to feel under any pressure whatsoever.
"The goal is to win the match," Alonso said this week. "If this happens, we will be five points away. We are not afraid, we are not nervous. I am really not worried."
Bayern shouldn't be either, though, and that's why this clash has such global appeal. Leverkusen are more than capable of breathing new life into the title race, but Bayern could just as easily kill it - and effectively break the Kane curse in the process.
