BERLIN: Bayer Leverkusen won a Bundesliga derby 2-0 at 10-man Cologne on Sunday to go 10 points clear at the top of the table and stretch their unbeaten run all season to 34 matches, reported German news agency (dpa).

Cologne’s Jan Thielmann was sent off 14 minutes into the game for a reckless challenge against Granit Xhaka, and Jeremie Frimpong opened the scoring in the 37th.
