Oscar played in midfield for Brazil and helped his side defeat Croatia 3-1 in the opening match of the 2014 Fifa World Cup.
But before I talk about what he did, I have to talk about how big the game was.
Brazil have won the most world cups in history (five), making them the most successful footballing nation on earth.
However, they are missing one rare gem.
They have not won a World Cup at home in front of their own people.
The whole world expected them to perform yesterday and their fans, across the country, expected them to win.
The stage was simply made for big game players.
After 90 minutes of football yesterday morning, Brazil came away with the win.
You could argue moments of controversy won them that game.
But there were also heroes. Big game players in that Brazil team who rose to the challenge.
And none stepped up like Oscar. He was involved in every goal and created chances every time he touched the ball.
He even scored himself a nice toe-poke near the death (if there is such thing).
After the game, I simply had to give Oscar the top compliment: a big game player.
And something tells me he's not the only one we'll see this Fifa World Cup.
