FC Schalke 04's home advantage is put to the test as they host high-flying 1. FC Union Berlin, who sit just outside the European qualification spots. The away side has been on a rich vein of form, winning their last three league matches, including a crushing 4-0 victory over Bayer 04 Leverkusen. Can Schalke break the Union's momentum or will their opponents continue their surge up the table?
