Collina asked for protocol to be updated so the VAR could step in if a foul occurred before the ball was in play.
There have been several examples, such as a goal scored by England in their 1-1 draw against Uruguay at Wembley in March.
Cole Palmer delivered a corner into the area, but before the ball was kicked Adam Wharton blocked the run of Jose Maria Gimenez.
That allowed the ball to run through to Harvey Barnes, who saw his effort saved by Fernando Muslera, and Ben White tapped in from close range.
VAR protocol did not previously allow a review for a foul before a corner has been taken, but the Italian asked Ifab for permission to change this.
The Ifab has now accepted the request, and says that any foul that has a direct impact on a goal which happens before a set-piece is taken and leads to a penalty kick or disciplinary sanction can be reviewed.
The measure will be applied for the World Cup and reassessed after the tournament.
It means that for the England goal, the VAR would be able to suggest a retake of the corner because of the foul by Wharton on Gimenez.
“We think this is very unfair, that the goal is given when the defender is prevented from being able to defend,” Collina said.
“A clear, illegal block made by an attacker. The only objective was to prevent the defender from being able to defend on his opponent.
“We are very confident to receive a clarification from the Ifab before the World Cup, saying that the VAR can intervene just before the ball is in play. We are convinced that nobody can object.”
This will only apply to attacking fouls, and not to defensive fouls for holding or pulling.
Collina also explained the new rule for players who cover their mouth with a hand, arm or shirt in confrontation with an opponent.
This will now be a red card after the controversial incident involving Benfica winger Gianluca Prestianni and Real Madrid’s Vinicius Jr in a Champions League game in February.
Prestianni received a six-game ban from Uefa for homophobic conduct.
“If the conversation is friendly, they can continue to do it without any problem,” Collina said.
“When the conversation is confrontational, covering the mouth means that you are doing something very wrong, potentially, and the sanction is the red card.”
Collina also said his referees would be ready to monitor grappling inside the area, with officials provided with data on the tactical approach of teams.
