Wang Shuo's assist and Balik's goal brought the match back to a deadlock.
Although Cologne had the upper hand, they failed to break through Mainz's goal again.
The first half ultimately ended in a 1-1 draw.
But the players had expended a tremendous amount of energy in the match.
When they returned to the locker room, the Mainz players were all panting like bulls.
Klopp followed the players in. Before they could even get back to their seats, he forcefully slapped the small blackboard behind him.
"Find your seats and sit down! Not a sound! Listen to me!"
Everyone felt the head coach's intimidating presence and immediately returned to their spots.
"First off, we played terribly in the first half. It was a mess."
Klopp pointed at the players, his expression severe, looking like he was just one step away from unleashing a torrent of curses.
"I told you, Cologne's greatest strength is on the two flanks, especially on Ozat's side. But what happened?"
