FIFA president Gianni Infantino has spoken in favour of introducing the 'daylight' principle to the offside law to bring extra clarity.
There has been a great deal of controversy over offsides in the Premier League this season, with a number of goals ruled out by very fine margins after VAR checks.
FIFA's chief of global football development Arsene Wenger said last week that the law should be changed so that a player is onside if any part of their body that can score a goal is behind or level with the relevant defender, a view which Infantino clearly shares.
"I'm certainly in favour of discussing a new way of looking at the offside rule, to see if it can help, because I think the issue is more an issue of understanding," he said as he arrived in Belfast for Saturday's annual general meeting of the International Football Association Board, the game's law-making body.
"Some of (the decisions) are very, very close and it's difficult for the people who are watching to see whether it's offside, so we have to look at whether we can make the offside rule clearer by having light in between."
There can be no change to the offside law at this weekend's meeting because any alterations would have to go through the proper process and be examined by IFAB's football and technical advisory panels.
But the comments clearly indicate the direction of travel on offside as Infantino sees it.
Asked whether some leeway could be introduced on VAR reviews, he said: "It doesn't solve the issue.
"Even if you put a margin of 10 centimetres and then if it's 11, it's still one more, if it's 10 and a half... so it doesn't solve it. It should be clear."
Infantino agreed when asked whether the debate about offside was one that only seemed to be happening in England.
"In Italy, in Spain, in Portugal, in Germany this offside discussion is not existing on the VAR," he said.
"But it's not a problem, it's something to look into. And maybe it shows that actually it's more a question of the rule and the application of the rule, and application of the VAR itself."
Meanwhile, concussion substitutes could be trialled at this summer's Olympic Games, according to Infantino.
Football's handling of head injuries is set to be looked at.
Infantino agrees in principle with the idea of concussion substitutes - but believes these should be permanent if a concussion is diagnosed or suspected, not temporary.
And he believes the Games in Tokyo would be an ideal testing ground.
"This is a subject that needs to be discussed more and trialled as well," he said.
"Personally I believe more in permanent (substitutes) than temporary. That's my personal view. Maybe it's important there are trials before next season.
"We have the Olympic Games for example where we could, as FIFA, trial something like that and see what happens."
World players' union FIFPRO favours the introduction of a 10-minute assessment period for players suspected of having concussion, arguing that three minutes is simply not enough time to do it properly.
Its chief medical officer Dr Vincent Gouttebarge, who was part of the expert group whose advice has been passed on to the IFAB decision-makers, favours a temporary substitute coming on during
