Former Arsenal and FA vice-president David Dein has backed the idea. He told a FIFA Congress in Bangkok earlier in May: "The offside rule has to change as it is too contentious and problematic. Arsene’s idea is refreshingly innovative."
Wenger has been working on the proposal for four years and said the following back in 2020 about the offside rule: “There is room to change the rule and not say that a part of a player’s nose is offside, so you are offside because you can score with that. Instead, you will be not offside if any part of the body that can score a goal is in line with the last defender, even if other parts of the attacker’s body are in front. That will sort it out and you will no longer have decisions about millimetres and a fraction of the attacker being in front of the defensive line."
