South America has not produced a World Cup-winning side for two decades because so many of their players are spread across the globe, Colombia coach Reinaldo Rueda has suggested.

Brazil were the last nation from the continent to win the biggest prize in football, triumphing at the 2002 World Cup in Japan and South Korea.

Since then, Italy, Spain, Germany and France have all won the title, with only Argentina coming close from the CONMEBOL confederation when they finished second at Brazil 2014.

Brazil and Argentina will be among the favourites at Qatar 2022 later this year following superb qualification campaigns, alongside a host of familiar European rivals chasing success.

Asked ahead of Colombia's final qualifying clash with Venezuela this week – in which they must at least draw and rely on results elsewhere, too, to make an inter-confederation play-off – Rueda offered an explanation for why CONMEBOL sides have come up short over the past four editions.

"Without doubt, [players playing in Europe] has always been our biggest worry, the problem that we have in South America," Rueda stated. "I have said so many times.

"South America, with the potential and talent that it has, we are approaching now 20 years without a World Cup winner because of that situation.

"Because our biggest talents go to Europe and for some of them, it is difficult, depending on the percentage of those players that are in the national teams, to respond in the same way.

"Then players coming from Europe must attend two or three tournaments. South America has been a victim of this problem in the last 20 years

"That has been a factor that explains why strong national teams haven't been able to consolidate good performances and to win a world title that hasn't happened since 2002."
