Nah, what actually happens is a load of Manchester United fans see McTominay's name in the starting lineup then, at some point in the game, think to themselves...
"Where the feck is Scott McTominay? I mean, he's a big lump of a lad, so should be easy enough to spot but I'm following the ball round the pitch and I just don't see him. What the feck is going on?"
Then, after the game, many of these fans try to solve this mystery by looking at some stats and discover that this player - who was playing as part of midfield diamond with three other players in similar roles - seems to have been a bit of a statistical outlier:
Bruno had 93 touches and attempted 84 passes
Eriksen had 62 touches and attempted 61 passes
Casemiro (subbed off after 64 minutes) had 52 touches and attempted 46 passes
McTominay (subbed off after 85 minutes) had 22 touches and attempted 17 passes
IF HE'S NOT FECKING HIDING FROM THE BALL, WHAT THE FECK ELSE IS GOING ON HERE?!?
