Mastantuono Shatters Messi's Record with Hat-Trick in Serie A
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 clarity and composure, dragging Fiorentina to a 4-2 win over Venezia and straight into the record books. By the final whistle, he had not only rescued his new club’s season start but also stepped past Lionel Messi on a list that usually feels untouchable.
A record that used to belong to Messi
At 19 years and 28 days, Mastantuono is now the youngest Argentine ever to score a hat-trick in one of Europe’s top five leagues. Messi held that mark for years, his first Barcelona treble coming against Real Madrid in March 2007.
Mastantuono beats him by a staggering 231 days.
For Fiorentina, those numbers meant something very simple: their first points of the new campaign and a jump to 15th in the table. For the teenager, they marked a night that could redefine the trajectory of his European career.
From early setback to ruthless response
It didn’t start like a coronation. It started with a warning.
Venezia struck first in the 22nd minute. Akor Adams finished off a sharp move, with American midfielder Gianluca Busio threading the key pass after neat build-up play. The hosts had the lead, the crowd, and the momentum.
Then Mastantuono flipped the script.
Around the half-hour mark, he struck twice in the space of just one minute and 38 seconds. Two quick, clinical blows that turned anxiety on the Fiorentina bench into a surge of belief. By the time the clock ticked past 30, he had already become the youngest player in Fiorentina’s history to score multiple goals in a single match.
The pressure from Venezia never completely faded, but the teenager looked like he was playing to a different rhythm. Six minutes from time, he completed his hat-trick, sealing the points and his place in Serie A headlines in one swing.
A prodigy trying to reset his European story
For those who watched him explode at River Plate, none of this felt entirely out of nowhere. Mastantuono made his senior debut there at just 16, instantly tagged as one of the brightest talents in world football.
Real Madrid moved decisively in the summer of 2025, beating Paris Saint-Germain to his signature and tying him down on a six-year contract. That same month, he became the youngest player ever to represent the Argentina national team. The path looked straight: River Plate wonderkid to Bernabeu star to Albiceleste mainstay.
Reality bit harder.
His first season in Spain was a grind. Minutes were there, but the impact was not. Three goals in 35 appearances for Madrid told the story of a winger still adjusting to the pace, the scrutiny, and the demands of life at the Bernabeu. The dip in form cost him dearly: when Argentina named their World Cup squad, his name was missing.
The loan to Fiorentina, on paper, looked like a reset button. In practice, nights like this are what it was really about.
He has already matched last season’s Madrid goal tally in just five games for the Viola across all competitions. The confidence that seemed to drain away in Spain is suddenly back, visible in every first touch, every decision in the final third.
A platform, and a warning
This season-long spell in Italy now feels less like a temporary detour and more like a launchpad. Fiorentina badly needed a spark; Mastantuono has given them one. He needed a stage that allowed him to make mistakes, to take risks, to dominate the ball. Serie A, on this evidence, might be exactly that.
For Argentina, his performance in Venice will not go unnoticed. A World Cup squad passed him by, but if he keeps this kind of edge in front of goal, another call from the national team setup will feel inevitable rather than hopeful.
One hat-trick has already taken a record from Messi. The real question now is how far this teenager can push the story from here.
