Hosts Brazil are waiting anxiously to see whether FIFA will rescind the suspension of their captain Thiago Silva for Tuesday's semi-final with Germany while Argentina must make up for the sizeable absence of Angel di Maria for their clash with the Dutch.
If Brazil's appeal against Silva's booking in the bruising quarter-final with Colombia -- which saw Colombian playmaker James Rodriguez get particularly rough treatment which went unpunished -- is successful his return would compensate a little for the absence through injury of their star player Neymar. (Brazil may excel without Neymar, says Schweinsteiger)
The card against Silva was "unjustly shown" and the defender should therefore be allowed to face the Germans in Belo Horizonte, the Brazilian Football Confederation (CBF) said in a statement. (One hand on trophy, big Phil dreams big for hosts Brazil)
