Harry Maguire insists Manchester United were robbed of a penalty against West Brom fter a VAR review led to referee Craig Pawson overturning his decision to award a spot-kick.
The Red Devils captain tumbled under the attentions of Semi Ajayi and, despite initially deeming it a foul, the match official changed his mind after reviewing a replay of the incident.
"I was certain it was a penalty," said Maguire.
"I don't understand why he has even gone to the monitor. I felt a tug on my shoulder, it was slight, but there was also a clip on my heels and I was confident it was going to be given as a penalty.
"But it seems decisions are going against us at the minute, although we can't rely on VAR decision, we've got to do more in the game."
United boss Ole Gunnar Solskjaer, meanwhile, has no intention of settling for second place, despite his disappointment at only claiming a draw at The Hawthorns.
Having been top of the Premier League just 19 days ago, his side now sit seven points behind leaders Manchester City, who have a game in hand.
"It's disappointing, of course. We've come away with two points less than we wanted to," said Solskjaer. "The start was difficult. They put us under pressure as you expect when they get a kick-off and we couldn't clear our lines.
"Then again, we get 90 minutes-plus to get two goals. I'd rather concede in the first than 92nd minute."
Asked if United were now playing for second spot, Solskjaer said: "No, I don't think so. I think no one will give it away this early.
"Of course no one knows this season, it's so unpredictable, life is so unpredictable. Anything can happen.
"We're not going to settle for second, of course we're not."
On the penalty controversy, Solskjaer added: "I think we all want consistency and a fair game. But then again there's human error that we all expect from our game. That's what happens.
"But the penalty we could have had today, it's a clear foul. If you only look at the clash between the centre-back and Harry, that's a foul.
"But from what I see, I see Harry being in an offside position, so someone must have been asleep in that VAR office at Stockley Park or wherever they are.
"Someone needs to brew some coffee because it could've easily been avoided by saying, 'Nah, he's offside, let's move on'."
