Ruben Neves was furious that a "clear foul" by Paul Pogba was not given in the build-up to Manchester United's winning goal at Wolves.
The Red Devils claimed a 1-0 Premier League victory at Molineux on Sunday courtesy of Mason Greenwood's strike with 10 minutes of normal time remaining.
The result moved United to seven points from their first three games and stretched their unbeaten run away from home to 28 games, a record in English league football.
However, Wolves were incensed that the goal was allowed to stand, with Pogba having caught Neves low on the shin in a 50-50 challenge on the edge of the home side's penalty area shortly before debutant Raphael Varane teed up Greenwood.
Referee Mike Dean allowed play to continue, much as Craig Pawson did in United's previous game at Southampton when a robust challenge on Bruno Fernandes prior to Saints' opening goal went unpunished.
Speaking to Sky Sports, Neves said: "Everyone saw it, everyone saw my leg. We always do meetings and everything with referees about VAR. I don't know why.
"They said before the season started they will look for contact – if the contact is strong enough, they will give the foul. I showed them my leg.
"I think maybe because last game it was a foul before the Southampton goal, maybe now they did the opposite. I showed my leg to the ref, I showed [it] to the assistant ref, I cannot say anything more.
"After the game, he said 'you both go to the ball' and I said 'yes, we both go to win the ball but I was the one who touched the ball'. It's a foul, a clear foul."
Sky Sports pundits Roy Keane and Graeme Souness agreed, with the former Liverpool midfielder branding the challenge "a leg-breaker", but Pogba was adamant there was no reason to award a free-kick.
"My view is this is the Premier League, it's a 50-50. Every weekend, that is happening," he said.
"I need to see it again, but I didn't touch him. I won the ball and we scored. I need to see it again."
