Lionel Messi is widely considered the world's best soccer player. But he has time for fans.
Security didn't stop the fan, who live-tweeted his plan and had a friend livestream it.
Messi was playing for Argentina in the Cópa Americana, a soccer tournament for the nations in the Americas.
Argentina beat the U.S. in the semifinal 4-0 and will play either Colombia or Chile in the final Sunday night.
Also, Messi scored this goal on a free kick, and every soccer fan watching went insane.
