Leipzig cut Bayern’s lead to five points with six rounds remaining with a 4-1 win at Werder Bremen.

Bayern coach Hansi Flick, who said Friday his squad wasn’t as strong as the previous year’s, started with reserve players Josip Stanisic and Tiago Dantas. It was a debut for the 21-year-old Stanisic, a defender, and first start for Dantas.

Bayern’s injury worries deepened after about half an hour when Kingsley Coman needed treatment on his left knee, but the France attacker continued till the break, when he was substituted by Leroy Sané.

Ingvartsen’s equalizer cost Bayern two points, however, and kept Union flying high in seventh place.

Fourth-place Eintracht Frankfurt enjoyed a 4-3 win over third-place Wolfsburg, and Hertha Berlin could only draw 2-2 with Borussia Mönchengladbach despite playing most of the game with a player advantage after Yann Sommer’s early sending off for the visitors.
