Angel di Maria scored an extra-time goal to fire defending champions Argentina into the Olympic semi-finals with a 2-1 victory over the Netherlands on Saturday.
Argentina's win set up an interesting last four clash with arch-rivals Brazil after the latter beat Cameroon 2-0.
Barcelona star Lionel Messi had opened the scoring for Argentina in the 14th minute before Otman Bakkal drew the Dutch level 11 minutes before half-time.
