Chelsea goalkeeper Thibaut Courtois has withdrawn from Belgium's squad to face Saudi Arabia due to an ongoing hamstring complaint and is now a major doubt for Sunday's clash with Tottenham.
Antonio Conte confirmed Courtois was suffering from a "muscular problem" ahead of last weekend's FA Cup quarter-final win over Leicester City, although understudy Willy Caballero usually starts domestic cup games.
Courtois joined up with Roberto Martinez's national side but Belgium have confirmed he will continue his rehabilitation with the reigning Premier League champions and play no part in Tuesday's friendly.
"Thibaut Courtois has not recovered from his hamstring injury and left the group," read a statement issued on the team's official Twitter page.
