The opening day of the Olympic men's soccer tournament delivered two stunning results.
Brazil won the showcase fixture of the round over Germany. The Selecao hit three goals past the Germans in the first half but were pegged back to 3-2 with just five minutes remaining in the game. However, Bayer Leverkusen winger Paulinho struck in injury time to seal the victory.
Mexico knocked off another European power in France earlier on Thursday morning by way of a four-goal onslaught.
The performances from Brazil and Mexico put them firmly at the top of the gold-medal favorite discussion.
