Neymar's fitness will be under the microscope on Friday as Brazil try to kickstart their World Cup campaign, anxious to avoid the kind of pitfall that has left Argentina and Lionel Messi facing an early exit.
That means Paris St Germain star Neymar will retain his place despite limping out of training during the week with an ankle injury.
Neymar then set alarm bells ringing when he hobbled out of training on Tuesday.

The scrutiny will be on Neymar, but Brazil have a team packed full of talent that can hurt Costa Rica.
This is the third meeting between Brazil and Costa Rica at the World Cup, with the former inflicting Costa Rica's first ever defeat on them at the tournament in 1990 (1-0), before a 5-2 victory in 2002.
