Everton boss Frank Lampard said his three-year-old daughter would have known his side should have had a penalty for handball in their 1-0 defeat by Manchester City.
A loose ball hit Rodri's outstretched arm in the box in the closing stages.
Referee Paul Tierney did not give a penalty and the video assistant did not think it was an obvious error.
"There is not a person who watches that... that can't see that's a penalty," Lampard told BBC Sport.
"Something has to be done about that."
Everton remain in relegation danger, one point above the drop zone, after Phil Foden scored the only goal at Goodison Park.
But Lampard could not believe his side were not given a spot-kick with five minutes to go.
He told Sky Sports: "VAR have two minutes to look at it and to think they have not given that as a penalty when it strikes him on the arm, in an unnatural position. I have a three-year-old daughter at home who could tell you that was a penalty."
The VAR, Chris Kavanagh, felt there was not conclusive evidence that the ball was more in the 'red zone' - the area below the sleeve line - than not, and that was it was not an obvious error.
Lampard added: "We've lost a point because of a professional who cannot do his job right. It is so incompetent to get it wrong.
"It was the clearest penalty you could give - arm is out - great, below the sleeve - great, I was waiting for the penalty.
"I'll wait for the statement or apology they do when things are wrong but it will mean nothing."
