Belgium coach Marc Wilmots has warned that even star attacker Eden Hazard is not assured of a place in his World Cup team.
The Belgians arrive in Brazil tipped as dark horses for the tournament with what is being heralded as a 'golden generation' that includes Hazard, Dries Mertens, Vincent Kompany and Adnan Januzaj among others.
And Wilmots says he has so much quality at his disposal that even the €40-million Chelsea star has to cement a starting berth.
"Nobody is guaranteed to start the game, even Hazard," Wilmots Sportwereld.
"Each player is perfectly replaceable."
However, when asked whether he had already settled on his starting line-up for their World Cup opener against Algeria, Wilmots said: "Of course. But I do not want you to know the team.
"I've also been through, as an analyst, the guesswork for the team. Now it's up to you to guess.
"This is a World Cup, I want to play hide and seek."
Wilmots' men kick off their campaign against Africa's top-ranked side, Algeria, before coming up against Russia and South Korea in Group H.
