France’s union of professional soccer players launched a scathing attack on the Club World Cup on Sunday, saying it is “urgent to stop this massacre” amid ongoing concerns about extreme player workloads.

The UNFP also accused FIFA president Gianni Infantino of living “in an ivory tower” by ignoring the impact congested calendars have on players worldwide.

“His [Infantino’s] Club World Cup proves, to the point of absurdity, that it is urgent to stop this massacre game. He flouts the physical and mental health of players for a few more dollars” the UNFP said in a statement.
