FIFA will sanction an increase from three to five substitutions per game when football returns amid the ongoing coronavirus pandemic.
That is according to referees chief Nicola Rizzoli who reckons football's governing body will accommodate the requests of individual associations.
The suggestion is that an increase in replacements will reduce the strain on players with fixture lists across the globe set to become more congested when matches eventually kick-off again.
Games are also set to be played in higher temperatures than normal with the Premier League hoping to restart in June and continue throughout the summer.
Rizzo - the Italian official who reffed the 2014 World Cup final - told Sky Italia: "I believe FIFA intend to allow five substitutions.
"In a phase of the season with many games one after the other and in elevated temperatures, we'll have to all take a step forward to help everyone."
Rizzo also revealed the changes referees will need to make, including a reduction in the number of officials in the VAR booth - and the protective equipment they will need to wear.
"We need to behave differently, including when it comes to social distancing, to avoid risks.
"We also require a cultural step forward that I hope can be positive for everyone. We are working with UEFA and other major leagues to set out the code of behaviour.
"We're also working to reduce risks to a minimum, as usually there are four people in the VAR booth, but it would be reduced to three, all of them wearing masks and protective gloves."
