FC Union Berlin hosts Bayer 04 Leverkusen in a pivotal Bundesliga clash. With Leverkusen seeking to maintain their title push, Xabi Alonso's men will face stiff resistance from Union's stingy defense, which has kept two consecutive clean sheets. Leverkusen's forward Julian Baumgartlinger will be closely monitored, given his impressive goal-scoring form, as he looks to exploit Union's backline.
