The young Spanish star, Lamine Yamal, who is only 17 years old, was the standout of one of the most important tournaments in the world. The Spanish player waved a blue and red flag during his team's celebration after defeating England 2-1 at Berlin's Olympic Stadium.

This flag went viral because no one knew where it was from. Many people even thought it was a Barcelona flag, thinking he was honoring the Catalan club during the celebration. However, the flag is actually from Mataró, a town in Barcelona where Yamal grew up.
