All do not seem to be well in the Belgium camp, following their 2-0 defeat to Morocco in the World Cup.
The Red Devils would need to beat Croatia in their final group game to qualify to the next round.
Speaking after their defeat to Morocco, Manchester City star Kevin de Bruyne slammed his teammates, as he claimed that Belgium are having problems due to their squad being too old.
Courtois has disagreed with the Manchester City midfielder over his views.
“It’s not an age issue,” Thibaut Courtois said when asked if Belgium’s struggles at the World Cup are due to players being ‘too old’.
“At Real Madrid we have Benzema and Modrić. It’s too easy to make that excuse,” he also said.
