At 1 am on June 2, 2026, on the red clay of Roland Garros, Matteo Arnaldi was down two breaks in the fourth set against Frances Tiafoe. He was losing. He was physically failing. He was about to exit a tournament into which he had entered almost on tiptoe, recovering from months of injuries and a ranking that had slipped beyond the hundredth place. But no. He won nine of the next thirteen games. He closed in the fifth set. When they put the microphone in front of him, he only said, “I don’t know how I can stand here.”
This is the phrase that explains Arnaldi better than any statistic. Not the technique, not the tactics. The fact that it doesn’t stop. Who manages to find something when there seems to be nothing left. Before following his run to the semi-final, it’s worth understanding where this guy is coming from. Because fairy tales don’t arise from nothing.
He was born in the city of the Festival
Matteo Arnaldi was born on 22 February 2001 in Sanremo. The same city of Fognini, the same Ligurian Riviera, the same sea. There is something in that corner of Italy that produces hard-headed tennis players with their feet on the ground. Maybe it’s the wind. Maybe it’s growing up knowing that every year the world looks at you for five days, then turns away.
He started with a grandfather and a wall
He started playing tennis at the age of five, dribbling with his grandfather against the wall of the sports club. No academy, no talent scout. Just a child, an old man, and the patience to learn the correct gesture blow after blow. It’s an image worth more than a thousand tactical slides.
Before choosing the racket, he tried everything
Up to the age of 12 he also practiced skiing, football, judo and above all swimming, before finally choosing tennis. This is not a marginal biographical detail. Those years of swimming, skiing and falling on the tatami built him a physique and a mentality that tennis alone would never have given. The resistance he shows in certain five-set matches also comes from there.
His father works in a bank, his mother in healthcare
Mrs. Silvia is an employee of ASL1 Imperiese; Mr. Arnaldi’s profession in the bank in the role of team manager is known. A normal family, in the fullest sense of the term. After the victory in the Davis Cup, father Fabrizio said on television that at the beginning of the year they didn’t even expect to see him play in a final, and that after the victory they celebrated at home, with their family. Not in Malaga. At home.
He has a younger sister named Sofia
He has a younger sister, Sofia. Almost nothing about her, like about the whole family – who chose to remain in the shadows with a coherence which, in the age of parents-influencers of athletes, is almost a form of elegance.
He attended sports science high school
In 2020 he obtained his high school diploma from the “Colombo” sports scientific high school in Arma di Taggia. While others at eighteen had already left everything for the circuit, he finished school. Small thing, perhaps. But it says something about how it’s made.
He returned to his club to start again
After the federal center in Tirrenia and the Milan Tennis Academy, at a certain point he made a choice that few would have understood: returning to Sanremo. In May 2021 he returned to training at the Circolo Tennis Sanremo, starting a collaboration with coach Alessandro Petrone. The circle has closed where it all began. A few months later, he was already in the orbit of the ATP circuit.
He is 185 centimeters tall and plays with a two-handed backhand
He is 1.85 meters tall, plays right-handed and uses a two-handed backhand. He is not a servant like Isner, he is not an acrobat like Alcaraz. His is a tennis of substance: solid, continuous, capable of wearing you down without you realizing it until it’s too late. Just like he did with Tiafoe.
He turned professional in 2019
He chose to turn professional in 2019, at eighteen. Then years of Challengers, of defeats in the qualifying rounds, of trips to places you can’t even pronounce the name. The normal path of those who were not born with hype around them. Perhaps this is why he knows how to resist better than others when things get bad.
The first Challenger title arrived in Francavilla al Mare
The first Challenger title arrived in Francavilla al Mare in 2022. An Adriatic town, not exactly the stage of dreams. But that win took him to Wimbledon for the first time — his first Grand Slam. True paths are made up of stages like this: invisible to others, decisive for you.
2023 was the year Italy discovered it
In 2023 the explosion arrived: the round of 16 at the US Open, the victory over Cameron Norrie, ten games snatched from world number one Carlos Alcaraz, and entry into the top 50. The general public discovered it that autumn. Those who followed him from before looked at him and thought: finally.
He won the Davis Cup as a protagonist
There is a moment that those who were there will never forget. Malaga, November 2023, final against Australia. Arnaldi took to the court for the first singles, faced Alexei Popyrin and beat him in three sets, paving the way for Sinner’s decisive point and bringing the Davis Cup back to Italy after 47 years. Then he dedicated the victory to his girlfriend, thinking of her father, who passed away a month earlier. «A month ago, a very important person died for my girlfriend, and also for me. This victory is for him.” In that sentence there was all Arnaldi.
Its best ranking is number 30
In August 2024, thanks to the semifinal in Montreal, he rose to 30th place in the ATP rankings — his career best ranking. It was the highest point. And as often happens with the highest points, from there the descent began sooner than expected.
In 2024 he achieved a silent feat at Roland Garros
At Roland Garros 2024 he eliminated Andrey Rublev, then world number 6, with a score of 7-6, 6-2, 6-4. Thirteen aces, 47 winners, 19 unforced errors. An almost perfect match, played in silence — in the sense that few talked about it enough. It was the signal that he could do important things on the red clay of Paris. The following year he would prove to have a good memory.
2025 was sidelined with a foot injury
A foot injury made him slip beyond 70th place and affected the entire 2025 season. Not a game crisis, not a mental problem: a body that stopped. Starting from there – with the ranking in pieces, the points to be rebuilt from scratch, the circuit that won’t wait – was probably the most difficult thing of his career.
The rebirth started from a Challenger in Sardinia
The spark was rekindled with the title at the Challenger in Sardinia, where he beat Hubert Hurkacz in the final with a clear 6-4, 6-4. Beating a former top 10 player in the final, with that ease, after months of stopping. It’s not a coincidence: it’s an answer.
He met his girlfriend thanks to a pizza in Perugia
The relationship with Mia Savio was born in 2022 in a completely casual way: she was in Italy for a language course, he was engaged in a Challenger in Perugia. The first date? A pizza dinner. Mia is Australian with Italian origins, a model, often present in the stands at important moments. A normal story, kept out of the spotlight with the same care with which the family has always protected their privacy.
For the first time three Italians in the quarterfinals of the same Slam
At Roland Garros 2026, for the first time in history, three Italian players reached the quarterfinals in the same Slam: Cobolli, Berrettini and Arnaldi. A historical fact that in another moment would have made headlines. This year it was almost taken for granted, and it is perhaps the most precise measure of how much Italian tennis has changed.
He is Global Brand Ambassador of Golden Goose
He is today Global Brand Ambassador of Golden Goose, an Italian lifestyle and sneaker brand, with which he has already participated in international photographic campaigns. Previously she was a testimonial for Le Coq Sportif. The leap in level even off the pitch tells where he is positioning himself, in the imagination and in the market. Sanremo entering international fashion, passing through a Slam semi-final.
He reached the semi-final starting from over one hundredth place
When Roland Garros 2026 began, Arnaldi was outside the top 100. They considered him a rebuilding player, not a final week candidate. With the semi-final reached, he will climb up to 24th position in the world. Seventy places in two weeks. On the clay where a year earlier he was unable to play due to pain in his foot.
+1. They call him “Arnaldo” and “The Wall”.
There are two nicknames going around the circuit, and neither came from a marketing department. The first is simply Arnaldo — a distortion of the surname that has become an affectionate term, the way in which fans on social media greet each of his comebacks with a certain exasperated tenderness, as you do with someone who makes you suffer but you can’t stop following. The second is more serious: The Wall. The Wall. Because Arnaldi gives everything back, keeps balls on the field that seem finished, transforms patience into an offensive weapon. Against Tiafoe, that night in June, he demonstrated that the wall doesn’t collapse — at most it cracks a little, then it holds. And he wins.
