BERLIN (AP) Thomas Mueller starred as Bayern Munich got back to winning ways in the Bundesliga with a 4-0 rout of Cologne on Saturday.

The home side needed 11 minutes to break the deadlock on a counterattack. Mueller sent Douglas Costa on his way and the Brazilian crossed for Arjen Robben, who appeared to score with his stomach.

Mueller crossed for Costa seven minutes later and for Robert Lewandowski's 14th league goal of the season in the 37th.
