Kepa Arrizabalaga undermined manager Maurizio Sarri by refusing to be substituted as Chelsea were beaten 4-3 on penalties by Manchester City in the Carabao Cup final.
Chelsea keeper winked at the camera after his bust-up with Maurizio Sarri.
Former Blues captain John Terry said: "You have to show that respect and come off. He's put an awful lot of pressure on himself."
Fellow Sky Sports pundit Jamie Redknapp added: "It's unique situation to want to change your keeper in the first place."
And Gary Lineker tweeted: "Wow. This is bonkers. Not sure I’ve ever seen a player refuse to be subbed. Extraordinary."
