Wolves boss Nuno was left fed-up with VAR after their 1-0 FA Cup defeat at Manchester United.
Wolves had an early Pedro Neto strike ruled out by the video assistant referee for a handball in the build-up. The game was decided by Juan Mata's superb winner.
Nuno said, "It was a good game of football, an even game. Both teams had chances.
"We didn't defend the goal well but we reacted well and were in the game. A proper game, I am disappointed to go out because it is frustrating when you perform well and go out.
"That's VAR, you cannot do anything about it. We are celebrating non goals - it doesn't make sense."
