Manchester United manager Ole Gunnar Solskjaer did not agree with VAR's decision to award his side the first of their two penalties in a 3-1 victory over Norwich on Sunday.
United cruised on the day thanks to goals from Scott McTominay, Marcus Rashford and Anthony Martial but could have scored more if not for seeing two efforts from the spot saved by goalkeeper Tim Krul.

The controversial call came just before the half-hour mark, when Ben Godfrey tangled with United winger Daniel James and referee Stuart Attwell initially seeing no foul. After a lengthy VAR intervention, however, he changed his decision.
Krul stepped up and saved Rashford's effort from 12 yards but neither manager could see the merits of Attwell's call after the match.
"VAR is there to help but when it takes ages like the first penalty, it is not a clean and obvious error," Solskjaer said.
"When it took that long, it is a signal that it should not have been."
Norwich manager Daniel Farke echoed Solskjaer's frustration but conceded it would not have made much of a difference to the outcome of the match.
"It's quite obvious it was a big mistake [for the first penalty]. The referee was right and it was Daniel James falling on the defender.
"I don't blame VAR for this defeat, we were not major enough in the first half."
