Cristiano Ronaldo must get permission from FIFA if he is to make his Real Madrid comeback against Racing Santander on Saturday.

Ronaldo was stopped by Real and FIFA from appearing for Portugal in this week's World Cup playoff against Bosnia (which they won 1-0 last night). As the second-leg will be staged on Wednesday, Ronaldo could play against Racing before the mandatory five-day break which FIFA insists upon players who do not appear for international duty.

Ronaldo will do ball-work on Monday at Real with the view to him facing Racing on Saturday.
