Timo Werner scored his 25th goal in the Bundesliga season as RB Leipzig kept pace with Borussia Dortmund in the race to finish in the top two by winning 4-2 in an entertaining match in Cologne.
The coveted attacker took advantage of a disastrous defense to score in a period of three goals in seven minutes in a maniac second half.
Leipzig remains two points behind Dortmund with five games left.
It was the first Bundesliga match to be played in June since 1995.
Cologne had taken a fast lead thanks to Jhon Cordoba, the attacker hammering in a rebound after a shot against the post.
But Patrik Schick quickly led the level of Leipzig and Christopher Nkunku sent them at halftime ahead with a nice twisted finish from Konrad Laimer's pass.
Werner scored easily when Cologne made an inexplicable match, and Leipzig goalkeeper Peter Gulacsi managed to catch the ball and send it back to goal with a long punt.
Anthony Modeste withdrew a goal with an excellent curler at 20 yards, but Dani Olmo immediately succeeded 4-2 from the edge of the box after a corner kick was cleared.
Cologne then received a penalty when Modeste fell, but referee Christian Dingert reversed his decision after a check from the video assistant referee's monitor.
