The Deutscher Fußball-Bund (DFB) warned that an increase in the regularity of football’s showpiece event could cause more injuries.
The DFB also expressed concerns that the women’s and junior World Cup tournaments would be overshadowed were the plans, spearheaded by former Arsenal manager Arsene Wenger, to be implemented.
“If either a men’s World Cup or European Championship takes plays every summer, the women’s and junior tournaments would be marginalized in the shadow of the men’s competitions,” the DFB said in a statement.
The German footballing body also said that it “would lead to a significantly increasing risk of injury” due to increased “physical and mental strain”.
FIFA claimed earlier this week that a majority of fans want the World Cup held more frequently.
They cited the findings of a survey commissioned by the organisation and conducted by IRIS and YouGov.
Many footballing figures have expressed concerns with plans outlined by Wenger, now Chief of Global Football Development at FIFA.
