One of the best player in the world looked stress when Argentina meet Croatia. He carried a big burden to meet expectations from his nation to win this world cup.
In the middle of match, Ivan Strinic of Croatia tackle Messi and Messi couldn't hold his patience anymore.
Messi looked very angry, that's unusual for Messi, because usually Messi is a calm player. Strinic apologized to Messi, but it looks like Messi couldn't control himself in this match.
Messi threw Strinic leg to one side, but he didn't get any punishment from his action.
Even a best player will stumble when they're under heavy pressured.
