Burnley are furious after Friday night's 1-1 draw with Luton.
Zeki Amdouni's goal appeared all set to earn them the three points, but Carlton Morris' header on 92 minutes was deemed legitimate after a lengthy VAR probe. Morris' goal stood despite Burnley complaints of Elijah Adebayo nudging goalkeeper James Trafford as Morris scored.
"I don't know what to say to my players. It's ridiculous," Clarets boss Vincent Kompany told BBC Sport.
"We'll get up and we'll keep going. It's not even in my nature to complain about this. I don't like this side of me. I told the lads 'I don't know what to tell you'. It's bizarre.
"Against Nottingham Forest we had a goal disallowed we got an apology for. It keeps happening. It's incredible.
"I don't get it anymore. What is this here? There's a clear attempt to stop the goalkeeper getting up."
Burnley defender Dara O'Shea added: "I can't get my head around the decision. None of us quite understands it and we don't get any information on the pitch.
"We're bitterly disappointed with the result. I keep going back to that decision and I just can't understand it."
