The eagerly-awaited Real Madrid debut of Ronaldo has been thrown into doubt after the player complained of pain in his left ankle after completing training on Monday.
The Brazilian was expectedto make his Real bow in Wednesday’s Champions League match against Genk, but the latest setback makes that unlikely.
Ronaldo had just overcome a muscle strain in his left leg and has not yet played a game for his new side since joining the European champions from Inter in a deal worth 30 million.
