Naturally, fans are growing restless, especially with Neymar's lack of production.
Brazil's coach, Rogerio Micale, has cautioned that this anger might have some adverse affects down the road, though.
"If we don't respect our best players they might not want to be with us any more." That, of course, seems pretty rash, but it's not without precedent.
Lionel Messi, who Neymar plays alongside at the club level with Barcelona, retired from the international scene in June.
A defeat sends them packing, and they'd need some help to survive with a draw.
