The Argentine ace sent the ball into the back of the net just after the 60th-minute mark.

He still needs three goals to join the 100-goal club in UEFA Champions League games, but Lionel Messi has already broken the 100-goal mark in European competitions with his goal against Olympiakos.

In a game where Barcelona were having some problems after Pique's red card, Messi put everyone to rest when he sent the ball to the back of the net via a free kick. Olympiakos' goalie put a hand to the ball, but he failed in his effort to keep it out.

Here's a complete breakdown of Messi's 100 goals in European competitions.

His club and the official Twitter feed for the UEFA Champions League celebrated the player's milestone.
