Thomas Mueller scored again as Bayern Munich defeated Hertha Berlin 2-0 to provisionally extend its Bundesliga lead to 11 points on Saturday. Mueller broke the deadlock with his 13th goal of the season in the 34th minute, seven minutes before Kingsley Coman scored after a brilliant move involving Javi Martinez and Jerome Boateng. Unbeaten Bayern, with 13 wins from 14 games, will be guaranteed the lead going into the winter break if Borussia Dortmund doesn't beat Stuttgart on Sunday. Hamburger SV defeated Werder Bremen 3-1 away in the Bundesliga's 103rd northern derby, and U.S. international Fabian Johnson scored twice for Borussia Moenchengladbach to salvage a 3-3 draw at Hoffenheim. Hannover routed Ingolstadt 4-0 at home. Mainz was still playing Eintracht Frankfurt as kickoff was delayed due to increased security measures.
