Arsenal boss Arsene Wenger would welcome a new substitutions law.
Wenger believes that allowing teams to make a fourth substitution during extra time would help to improve football as a whole.
Arsenal manager said. "Four substitutes is not stupid, I think it is an intelligent way to deal with the fact that sometimes you have extra time.
"There are plenty of rules which can improve our sport. You want to keep it simple and not to add too many rules, but one more substitute, why not?"
