Haller and Malen share in goal celebration that makes Dortmund at least day leader

NOS Soccer–
Borussia Dortmund has taken over the lead in the Bundesliga from Bayern Munich. In a gala performance against 1. FC Köln, it became no less than 6-1.
With smooth combinations, Dortmund played the visitors completely over, which already led to a practically unbridgeable gap at halftime (4-1).
Malen opens the ball
Raphaël Guerreiro opened the ball after good preparatory work by Malen. Haller made it 2-0 after a nice combination between Marco Reus and Guerreiro, and Reus signed for the 3-0 with a shot into the top corner. Only after Malen had expanded the score did Köln do something back through Selke.
After halftime, Haller was able to tap in from close range after a free kick hit the crossbar and Reus struck the goal after a combination with Malen and Haller.
The title battle is actually still mainly between Bayern and Dortmund, who face each other in the next round of games. Sunday Bayern plays another away game against Bayer Leverkusen, in which it can regain the lead by taking at least a point.
Union Berlin lost nine points in the last four duels and RB Leipzig is also fumbling badly. A 1-0 defeat against former Vitesse coach Thomas Letsch’s VfL Bochum took the deficit on Dortmund to eight points.
