The former Barca full-back did not know Messi, was not convinced after being reminded by Iniesta, and was taught a lesson by Messi

In the summer of 2004, Villarreal full-back Giulino Beretti moved to Barcelona as the team's starting right-back.

It was also in this year that Messi was promoted from the La Masia Academy to the Barcelona first team, signing the first professional contract of his career.

Brazilian Giulino Beretti is now 45 years old, but in 2004 the Brazilian player was at his peak.

After arriving at Camp Nou, Giulino Beretti was in charge of keeping an eye on the young Messi in training, and he was kindly reminded by Iniesta that Messi was quite good. However, Beretti was not convinced, and he tried to stop Messi in training.

Giulino Beretti recalled that he did not know Messi at the time, and during a training session he tried to deal with Messi, but Messi was unstoppable, and in a one-on-one situation, he was tortured by Messi and defeated by Messi.

The former Barca full-back said: "When I first trained with Messi, I never heard of him. Iniesta came to tell me to be careful of Messi because he was amazing. At the best of my career, Iniesta said to me, "Be careful." I'm at the top! But Messi is in training, and he doesn't care who his opponent is. That time it happened to be me. One-on-one, when I was even thinking about how to deal with him, he had already beaten me. That's it...... I wanted to block him, but I couldn't.

In the summer of 2007, Belletti left Camp Nou to join Chelsea.
