United visited Craven Cottage on November 4 and thought they had made the perfect start when taking the lead in the eighth minute.
Christian Eriksen floated a free-kick into the back post and Alejandro Garnacho played the ball back across the box, where McTominay was waiting to find the net with a simple finish.
McTominay began to celebrate and the referee&aposs initial on-field decision was goal, but VAR officials reviewed the move and subsequently disallowed it because Harry Maguire was interfering with play from an offside position.
The decision was controversial because Maguire, who was being marked by Fulham defender Tim Ream, was not in the immediate vicinity of Garnacho, but VAR footage has been released to clarify what happened.
The VAR officials decided Maguire was &aposattempting to play with impact&apos from an offside position and that&aposs why it was disallowed, although it was described as a &apossubjective decision&apos because he didn&apost touch the ball.
Sky Sports broadcast the footage on Tuesday night and PGMOL boss Howard Webb said: “Just being in an offside position in itself isn&apost an offence, it depends what you do in that position.
