Mastantuono Makes History with Hat-Trick for Fiorentina

Mastantuono didn’t just arrive in Serie A. He kicked the door down.

On a humid Friday night in Venice, the Real Madrid loanee produced a hat-trick of rare authority, dragging Fiorentina to a 4-2 win over Venezia and straight into the record books. Nineteen years and 28 days old, and already rewriting a page that used to belong to Lionel Messi.

A record falls

Until this game, Messi held the distinction of being the youngest Argentine to score a hat-trick in one of Europe’s top five leagues. That landmark, set in March 2007 with his famous treble for Barcelona against Real Madrid, has stood as a reference point for a generation.

Mastantuono has just undercut it by a huge margin. He is 231 days younger than Messi was when he hit that first Barcelona hat-trick. The scale of the achievement is stark: a teenager, on loan, in a struggling side, delivering a performance that now sits alongside one of the defining names of the sport.

His three goals did more than make history. They gave Fiorentina their first points of the new campaign and lifted them to 15th in the Serie A table. For a club already feeling the early-season pressure, this was a jolt of electricity.

From early shock to total takeover

It did not start like a night of celebration for Fiorentina.

In the 22nd minute, Akor Adams put Venezia in front, finishing off a move sparked by sharp work from American midfielder Gianluca Busio. The hosts had the lead, the crowd, and the momentum. Fiorentina looked vulnerable, again.

Then the teenager took over.

Around the half-hour mark, Mastantuono exploded into life, scoring twice in the space of just one minute and 38 seconds. Two rapid, ruthless finishes turned the game on its head and instantly made him the youngest Fiorentina player ever to score multiple goals in a single match.

From anxiety to belief in under two minutes. That’s what a real talent does to a team.

Venezia fought to stay in it, but the decisive moment was still to come. Six minutes from time, Mastantuono completed his hat-trick, killing off the contest and sealing a night that will be replayed every time his name is mentioned in the years ahead.

A prodigy finding his feet again

For those who followed his rise in Argentina, this felt less like a surprise and more like a reminder.

Mastantuono first burst into the spotlight at River Plate, making his senior debut at just 16. The hype was immediate, and the queue of elite European clubs formed quickly. In the summer of 2025, Real Madrid won that race, beating Paris Saint-Germain to his signature and handing him a six-year contract. That same month, he became the youngest player to represent the Argentina national team.

Then came the comedown.

His first season at the Bernabeu was hard. New country, new expectations, a squad stacked with stars. The winger struggled to impose himself, finishing the campaign with just three goals in 35 appearances. For a player tipped as one of world football’s brightest prospects, it felt underwhelming and, in the end, costly.

When Argentina’s World Cup squad was announced, his name was missing.

Florence as a proving ground

That setback has shaped this season. The loan move to Fiorentina is more than a change of scenery; it is a reset.

Italy offers him minutes, responsibility, and the space to make mistakes and learn without the Bernabeu glare. Already, the numbers tell their own story. Those three goals he managed across an entire season in Madrid? He has matched that tally in just five matches for Fiorentina in all competitions.

This hat-trick, though, is different. It is not just about statistics. It is about presence. About a young player stepping onto a Serie A pitch and dictating the narrative of a game his team desperately needed to win.

Fiorentina’s season is still in its infancy, their league position still precarious, but performances like this can tilt a campaign. They can also reshape a career.

If Mastantuono keeps striking with this kind of conviction, the questions will not be about whether he belongs at this level. They will be about how long Fiorentina can keep him, how quickly Real Madrid bring him back, and when Argentina decide they cannot afford to leave him out again.
