Derek McInnes has blasted the Scottish FA over the penalty controversy in Kilmarnock's semi-final defeat to Celtic at the weekend.
The Ayrshire side were denied what was a stonewall spot kick in the final moments of the Viaplay Cup tie, which finished 2-0 to Ange Postecoglou's men.
Hoops striker Giorgos Giakoumakis hauled Killie's Joe Wright to the deck inside the area as they looked to get on the end of a long throw in from Ash Taylor.
Willie Collum waved away furious protests from the Rugby Park players, as the Greek striker then subsequently scored up the other end of the park to seal the game.
VAR did not advise the on-field referee to review his decision at the pitchside monitor.
And McInnes is demanding answers from the SFA over that failure.
Ahead of the visit of Rangers tomorrow, the Killie boss said: “We don’t want to dwell on it but it has to be said it was the wrong decision. I spoke with the refereeing department and wasn’t satisfied with what I was told. For years, we as managers and clubs, supported the whole movement for VAR coming into Scottish football.
“We wanted to make a modern league, don’t get left behind and all the rest of it. We wanted to try and help the referees as such as we could. For years I’d phone Hugh Dallas, John Fleming or Crawford Allan with grievances over decisions and they’d always say that the referee only had one look at it, only one chance, or his view was blocked and if he could see it as he sees it now it would be different.
“We’ve now, as clubs have put so much outlay for VAR, have the ability to look at it again. We were deserving of someone looking at that incident again.
"We had 8000 fans who made the effort to go to Hampden and sit in the rain and support their team. We were deserving of someone to go and make the effort to look at VAR and check that incident. It’s a penalty kick all day long and nobody has said anything different to me.
“The incident, in a semi final stage, was exactly the type of stage we brought VAR in for. We were deceiving of someone taking the time to look at it again. If they arrived at the same conclusion that would have been more worrying but they should still have made the effort.”
