Bayern Munich routed Borussia Monchengladbach 5-1 here in its first Bundesliga game since clinching a 6th consecutive league title. Head coach Jupp Heynckes had promised that Bayern would be fully focused despite having wrapped up the 2017-2018 championship last weekend, and his team lived up to those expectations at Allianz Arena after conceding an early goal on a Josip Drmic strike in the ninth minute.
