Leverkusen slay Bremen to return to Bundesliga summit
FootballBayern thrashed by Eintracht Frankfurt in Bundesliga
Bayern Munich suffered a jolt to their title defence, losing their first league game of the season 5-1 in Frankfurt and handing Bayer Leverkusen the chance to open a six-point lead at the top of the Bundesliga.
In a wet and wild contest in Frankfurt, the hosts raced into an extraordinary 3-0 first-half lead, with Omar Marmoush, Junior Dina Ebimbe, and Hugo Larsson scoring the goals as Dino Toppmoeller's side outmuscled a timid Bayern.
Joshua Kimmich dragged Bayern back into the match just before half-time but French midfielder Ebimbe had other ideas, capping a scintillating counter-attack after a mistake by Dayot Upamecano to make it four.
Ansgar Knauff added a fifth to put the game out of reach for Thomas Tuchel's side to complete a memorable performance for Frankfurt, who become the first team to score five goals against Bayern in the first 60 minutes of a league game since Frankfurt themselves, in 1975.
