Bayer did not miss the opportunity to widen the gap at the top of the Bundesliga this Sunday.
In this 24e lifting the championship, while Bayern was held in check by Friborg on Friday evening (2-2), Leverkusen did what was necessary on the Cologne pitch (0-2).
Thielmann was quickly expelled among the locals (14e), the visitors were able to make the difference through Frimpong (38e) and Grimaldo (73e).
So here is Bayer, still undefeated this season, with a ten-length lead over Bayern in control of the German elite. Remember that Leverkusen has never been German champion.
