Conmebol, the South American soccer federation, is lobbying Fifa to stage the World Cup every two years.
The proposal, by Conmebol president president Alejandro Domínguez, comes in the wake of the early success of the Uefa Nations League.
Sepp Blatter, Fifa’s former president, first floated the idea of a biennial World Cup in 1999.
“The proposal we have made to Fifa is to play the World Cup every two years and not every four,” Domínguez said. “Instead of having the Nations League in between we can just go ahead every two years and have a World Cup and that is for everyone.
“It’s for the players because they could play four World Cups if we move to a two-year cycle. If we stay with this format many players will not be able to play more than two.
“There are many solutions. We could hold the tournament in Europe, South America, North America, Africa and Asia without such a long wait. So we see an opportunity there and there is a proposal put forward to Fifa.”
Meanwhile, Conmebol is backing Fifa president Gianni Infantino for re-election in 2019.
