Gerard Pique and Antoine Griezmann could be heard reacting to the intense Paris Saint-Germain pressure during Barcelona's 4-1 loss at Camp Nou on Tuesday.
The cameras picked up Pique pleading with his teammates to keep possession for a sustained period of time in the build up to half-time.
The exchange went:
Pique: "Keep the ball, fucking hell, for fuck sake, come on! Fucking hell, keep the ball."
Griezmann: "Calm down, stop shouting, don't shout, for fuck sake!"
Pique: "Fucking hell Grizi, fuck me! No! Fuck off, we're suffering, we've been (pinned back) for five minutes."
Griezmann: "Don't shout at me! I'm suffering as well."
Pique: "Fucking hell, we're running like crazy"
Griezmann: "I am running like crazy, too"
Ter Stegen: "Come on, come on, mark your men"
