Thibaut Courtois has accused the football associations of putting money above the welfare of the players, who he believes are being treated like “robots”.
The Real Madrid goalkeeper played in both Belgian Nations League games during the current international break.
This also includes the game for third place with Italy on Sunday, which triggered the 29-year-old’s criticism.
“This game is just a money game, we have to be honest,” he told Sky Sports.
“We just play it because it’s extra money for Uefa and it’s an extra game on TV.
“OK, it’s a good game for us because it’s against Italy and for Italy it’s a good game because it’s against Belgium, but look how much both teams have changed their players – if we both made it to the final others would have played. “
Strikers Eden Hazard and Romelu Lukaku were two of the absenteeists for Sunday’s game, which Italy won 2-1. The players suffered from muscle problems after losing to France in the semi-finals three days earlier.
“It just goes to show that we are playing too many games,” Courtois continued. “Next year we have a World Cup in November, we may have to play again until the end of June. We will get injured and no one will care about the players anymore.”
“After a long season we will have to play four games in the Nations League again, we have two weeks vacation and that is not enough to be able to continue playing at the highest level for 12 months.
“If we never say anything, it will always be the same. They (Uefa) can be angry that other teams are forming a Super League, but they don’t care about the players, they just care about their pockets.”
Uefa told BBC Sport: “The Nations League has not increased the total number of national team games. It will be played on dates of the international game calendar.
“Its introduction should support national team football with meaningful, balanced and exciting games at all levels, which actually happened because all teams have goals to achieve in the competition.
“Uefa does not keep any revenue from the Nations League, which is passed on in full to its national associations. These revenues fund the organization and promotion of football across Europe.”
The world association Fifa is proposing further changes to the football calendar, according to which a world championship will be held every two years instead of the current four.
“You hear that they want to host a European Championship and a World Cup every year,” added Courtois. “When will we rest? Never.
“In the end, top players will get injured all the time and that’s the end. It’s something that should be much better and better taken care of. We’re not robots.”
