Uruguay -v- Brazil (21:50 Maracaibo)
Mexico -v- Argentina (21:50 Puerto Ordaz)
Uruguay and Brazil were both poor in the group stages but came to life on Saturday once they reached the knockout stages and their semi is a South American clásico with a huge history.
The Mexico-v-Argentina match-up has less tradition but these two teams have been in great form since the tournament started and been its two most consistent sides both with high-scoring classy attacks.
Two mouthwatering prospects.
