That was scary lol, this man is so passionate, but things were slightly different: Subotic went back in game but he wasn't able to take position. Klopp wanted the whole thing to wait untill Subotic would be back in his position.
Exaggerated request & reaction.
Hulk mode activate.
Made my day. :')
Basically what happened was that Subotic was waiting to re-enter the pitch after being treated for injury, but Higuain scored in the meantime whilst the fourth assistant and the referee told Subotic to wait. Klopp was enraged by this decision, and got sent off for getting angry and screaming at the assistant. It's really funny, but I can understand how he felt after he saw the Higuain goal. :P
