Fifa says it is happy to discuss the football calendar with the bodies threatening legal action.
Last week the European Leagues, which represents 39 leagues in 33 countries, and global players’ union Fifpro announced the action over what they say is Fifa’s “abuse of dominance” in the game.
In May the World Leagues Association – which includes 46 leagues including the Premier League – said it could go down the legal route if Fifa continued with plans to host a 32-team Club World Cup at the end of next season.
It comes following growing pressure over the number of games added to the calendar and the impact on players.
A Fifa spokesperson said: “Fifa has reiterated an invitation to meet and discuss the calendar with World Leagues Association and Fifpro, having received no response to a letter on 10 May 2024.
“Fifa believes there is a more productive way forward for football than the threat of legal action and the offer to engage in dialogue remains on the table.
“Fifa serves and balances the overall interests of world football, including the protection of players, and always strives to do what is best for the game around the world.”
