After Leipzig had crashed to a 2-0 defeat at Eintracht Frankfurt, Bayern seized the chance to trim their advantage with an emphatic win over David Wagner’s young Schalke side. Lewandowski and Thomas Mueller scored first-half goals, then both had efforts disallowed for offside by the video assistant referee (VAR). However, Leon Goretzka, Thiago Alcantara and Serge Gnabry netted second-half goals as Bayern dominated at the Allianz Arena. Leipzig have tough games coming up as they host third-placed Borussia Moenchengladbach on Saturday, then visit Bayern on Feb. 9. Union Berlin bounced back from their defeat at Leipzig with a 2-0 home win over Augsburg, with goals from Neven Subotic and Marcus Ingvartsen.
