UEFA president Aleksander Ceferin has yet to give his backing to FIFA president Gianni Infantino's proposal of boosting the World Cup from 32 to 48 teams.
In his first FIFA Council meeting last week since becoming one of the governing body's vice presidents, Ceferin heard of Infantino's idea to expand the international tournament.
"We didn't want to vote on it as it was too early," Ceferin said. "We simply didn't get any information about it. Nothing. Just shall we expand or not. We said we cannot say."
Ceferin is awaiting "proper analysis" on the merits of such a significant overhaul of the tournament.
