FIFA is threatening to ban players from participating in the World Cup if they also play in a breakaway European Super League.
Both FIFA and UEFA are opposed to the proposed European Super League.
"Either you are in or you are out," Gianni Infantino said, listing the World Cup, European Championship and national leagues as competitions that players from breakaway teams could be excluded from. "This includes everything."
FIFA is proposing a Club World Cup project that would be played every four years.
"The Club World Cup is the answer to any attempt to think even about any sort of breakaway leagues," he said.
