Wolves boss Nuno was left frustrated after their 0-0 draw against Leicester City.
Wolves had a goal ruled out by the video assistant referee as their Premier League game at Leicester City ended in a goalless draw.
Joao Moutinho's right-wing corner was headed goalwards by Leander Dendoncker and hit the arm of Wolves' Willy Boly at close range before Dendoncker shot the rebound past Kasper Schmeichel from eight yards out.
But, after a review, the goal was disallowed by on-field referee Andre Marriner, much to the frustration of some Wolves players.
"I thought it was a goal, we were ready to start again and VAR [on the big screen] said it might've seen something and I was surprised," said Dendoncker.
"Willy Boly was just jumping and I had no clue it was a handball. It's a new rule so we have to adapt to it and get used to it."
Wolves boss Nuno said the new rules could "ruin the game".
"I haven't seen the images but I trust them. If they saw it, what can we do?" he said. "Things that weren't [that way] before shouldn't be now. We have such a nice Premier League, such a product, we cannot lose that.
"It's what fans come for, to celebrate, not to celebrate a no goal - that's not the real celebration of football. It's not good for the atmosphere of football. The Leicester fans were celebrating the no goal, that's not the mindset of the game.
"What I'm concerned about is, let's not ruin the game."
