The scoreline was level and with five minutes added on both sides were aiming to secure victory late on in an enthralling contest.
In the 94th minute, Idrissa Gueye’s thumping drive was pushed back into the danger area by Amadou Onana and a combination of Maguire and De Ligt appeared to bring down Young.
Replays showed there was clearly a touch on the veteran full-back, but was there enough contact to send him tumbling to the turf?
The Premier League Match Centre said:, external “VAR checked the referee’s call of penalty to Everton for a challenge by Maguire on Young and deemed that no foul had been committed and recommended an on-field review.
“The referee overturned the original decision and play restarted with a drop ball.”
Asked about the Premier League’s explanation, Moyes said: “So did they look at the shirt pull? So they only mentioned the bit they needed to and not the shirt pull? It looked to me as though the shirt pull was enough.
“I am not an expert on VAR, I can only tell you what I have seen. You shouldn’t be getting away with pulling jerseys. From the touchline I thought he had gone over somebody’s leg.”
United manager Ruben Amorim added: “I think it was a soft touch from what I saw. I think it was a soft penalty, it was clear.”
Everton fans were left irate by the decision and loudly jeered Madley when he went down the tunnel at full-time.
