So, why was Pique so mad?

Well, Manzano only added on four minutes extra-time. According to Marca, Pique felt as if more stoppage time should have been played.

Due to the poor conditions, Manzano spent around five minutes trying to fix his technology, meaning Pique did have reason to protest.

@TheMessiguyy claims Pique said: "Let me speak, let me speak, you gave us a little extra time, and you've been off the field for a long time."

Ronald Koeman was also upset with how much time was added on.

“If you are a Barca fan you are angry, very unhappy, with two ref decisions. In first half we were not good," he said, per the Athletic's Dermot Corrigan.

"Second half we improved, and I just ask that the referee gets decisions right, as it is a clear penalty and way more than four minutes of added time.”
