Fifa president Sepp Blatter has proposed changing the fixture schedule of European leagues so that the season runs through the summer months.
Blatter feels more needs to be done to give players a rest
Blatter told Germany's Kicker magazine that the season should begin in late February and end in November.
He said: "I've just proposed to the clubs: play through the summer.
"This would leave enough time for players to recover and there could be blocks of three weeks of national teams' qualifying games in winter."
Blatter added: "This idea is supported by big European clubs."
And to further ease fixture congestion, Blatter believes there should be more European groups with fewer teams for World Cup qualifying.
He feels this would mean fewer games for national teams as urged by leading clubs.
