Spaniards Javi Martinez and Juan Bernat scored their first league goals of the season to give Bayern Munich a comfortable 3-0 victory at Cologne on Saturday and move seven points clear at the top of the Bundesliga. Central defender Martinez gave them a deserved lead in the 25th minute and fullback Bernat doubled it after the restart to make sure of Cologne's first home defeat in the Bundesliga since April 2016. Bernat then set up substitute Franck Ribery for their third goal in the final minute with Bayern on track for a record-extending fifth consecutive league title. The Bavarians, who travel to Arsenal next week for their Champions League round of 16 second leg, are on 56 points with RB Leipzig, who drew 2-2 at Augsburg on Friday, in second on 49. Bayern coach Carlo Ancelotti left Mats Hummels, Xabi Alonso, Arjen Robben and Ribery on the bench at the start with an eye on the Arsenal match. But their absence was never felt as Bayern dominated throughout with 20 shots on goal compared to Cologne's six. "We played an outstanding match," Ribery told reporters. "This win is also very important for our match (against Arsenal) on Tuesday." Borussia Dortmund, hosting Benfica on Wednesday for their own Champions League match, also made the most of Leipzig's slip-up, closing in to within six points in third place after Bundesliga top scorer Pierre-Emerick Aubameyang scored twice to help them demolish Bayer Leverkusen 6-2. Gabon international Aubameyang's two goals put him top of the scorers' list with 21 but Dortmund's Marco Reus limped off with a suspected thigh injury just before the break to put his participation against Benfica in doubt. Hoffenheim fought back from 2-1 down to crush Ingolstadt 5-2 and remain fourth on 41, two off Dortmund. New VfL Wolfsburg coach Andries Jonker, who succeeded sacked Valerien Ismael this week, failed to inject any new life into the struggling former German champions, who drew 1-1 with Mainz 05.
