The game between Vitoria and Porto was brought to a temporary halt after a fan walked onto the pitch and attempted to ATTACK the players.
The moment of madness happened in stoppage time when the ball went out of play.
The fan nonchalantly strolled onto the field of play and approached two Vitoria players.
He kicked the first player twice before turning his attention to another Vitoria player.
The crazed supporter tried to kick the player, but, fortunately, didn't connect as he missed kick.
Match stewards eventually appeared and restrained the person.
Naturally, the bizarre incident got fans talking online.
One tweeted: "It's quite amazing how easy he managed to get onto the pitch."
A second wrote: "The security is scarily lax."
A third added: "The guy literally walks onto the pitch as if he's lost."
After a brief stop in play, the game resumed.
Porto claimed all three points thanks to Mehdi Taremi's first-half penalty.
