While reports continue to suggest he could retire after the tournament, the veteran playmaker has not confirmed any decision regarding his future.
Modric has repeatedly stressed that his only focus is leading Croatia through the World Cup rather than discussing retirement or club uncertainty.
"I'm focused exclusively on the tournament because I want to help the team in the best possible way," he told media.
Ahead of their high-stakes opener against England, Modric delivered a defiant message, insisting Croatia fear no opponent on the biggest stage.
"We respect everyone, but we're not afraid of anyone. Now it's up to us to prove it on the pitch. We want to make all Croatians proud."
