Bayer Leverkusen moved 10 points clear at the top of the Bundesliga
After defending champions Bayern Munich were held to a 2-2 draw by Freiburg on Friday, Xabi Alonso’s side had a big opportunity to extend their lead.
Their task was aided when Cologne’s Jan Thielmann was shown a straight red card for a foul on Granit Xhaka.
Jeremie Frimpong then opened the scoring before Alex Grimaldo’s low strike made it 2-0 in the second half.
