Koln was leading then Leipzig scored at 20' by Pschik and it just scored now by Nkunku after a shitty defence failure. 2-1 for Leipzig for now
BTW koln goal was

That was a quite a game to see! It was a goal fest and If Leipzig were clinical enough they could score at least 2 goals more even in closing minutes.
Leipzig eventually lived up to expectations, after they went behind I wasn't thinking this could another night like the one against Freiburg, but their attitude was great the goal and overall it was a well deserved 3 points.
