Fifa’s calendar revamp would “lead to a direct and destructive impact on the club game”, says the European Club Association.
World football’s governing body has proposed a men’s World Cup every two years as part of an over European Club Association.
It rejected Wenger’s suggestion the new schedule would improve the competitive chances of smaller nations, and said the development of women’s football, with tournaments “deprived of exclusive slots and overshadowed by the proximity of top men’s events”, would be impacted.
The ECA added: “Aside from the notable lack of genuine (or indeed any) consultation, and as many stakeholders have pointed out in recent days, Fifa’s proposals would lead to a direct and destructive impact on the club game, both domestically and internationally.
“In addition, the proposals would put players’ health and wellbeing at risk. They would dilute the value and meaning of club and country competitions.
“They would diminish and conflict with women’s and youth football – being under-represented areas of the game where ECA and others are committing significant time, talent and resources – while also subordinating other sporting tournaments and interests at all levels worldwide.
“Given the centrality of the IMC to club football, and of club football to the IMC, ECA reiterates in the most unambiguous terms that any decisions relating to its future can only come about with the consent of football clubs, with player welfare at their heart – and in keeping with legally binding obligations which ordinarily should not need restating.”
