Immobile leaves the game with 350 goals in 656 appearances across spells at twelve clubs, most recently Paris FC, whose contract he terminated before confirming his decision, reflecting on a journey that took him from Serie A's lower reaches to a European Championship winner's medal with Italy.
His journey began with Sorrento and Juventus's youth ranks before loan spells at Siena, Grosseto and Pescara, where he top-scored Serie B and won promotion under Zdeněk Zeman. After a season at Genoa, he broke through at Torino, winning the Serie A Golden Boot in 2013-14 before a move to Borussia Dortmund and a loan at Sevilla. His return to Italy and transfer to Lazio in 2016 defined the rest of his career: he was Serie A's top scorer three further times in Rome and set the division's single-season scoring record with 36 goals in 2019-20, a haul that also earned him the European Golden Shoe.
In total he scored 207 goals in all competitions for Lazio, 201 of them in Serie A, placing him among the division's ten most prolific marksmen of all time, and won two Italian Super Cups and a Coppa Italia. He was part of Roberto Mancini's Italy side that won Euro 2020, delayed to the following summer by the pandemic, scoring twice during the tournament. After leaving Lazio in 2024 he had spells at Beşiktaş and Bologna before signing for Paris FC this year.
"I've enjoyed myself, I made the most of it. I pushed my body to the limit but I don't regret anything," Immobile said.
Asked about the high point of his career, he was unequivocal - it was winning the Euros with Italy.
"That was the peak of my career, an achievement I wish on everyone. It was a dream, something unique. The memories, the moments we shared together on and off the pitch will stay with me forever."
Immobile also spoke at length about the role his family played in his career, describing the sacrifices made by his wife in particular.
"I was lucky to grow up in a humble environment and that gave me incredible strength. I've tried to teach my children the values my parents taught me. Jessica [his wife] has been incredible, she took every step with me without ever making me feel the weight of all the moves. She left her family after three months of knowing me, from a small town in Abruzzo to Genoa. Without my parents, without my brother and without my wife I could never have reached this level."
On his time at Lazio, where he became the club's all-time leading scorer, Immobile was similarly effusive.
"Lazio was an incredible love story. I wish every footballer could bond with a club and its fans the way I did, managing to give more than you have. And Lazio allowed me to do that. I'm deeply attached to everything around the world of Lazio, it's left so many beautiful memories in my heart."
Looking ahead, Immobile confirmed he intends to move into coaching after a period with his family.
"Right now I'm spending some time with my family, then I'll start studying and doing a course to become a coach. It's something I enjoy doing, I'd been thinking about it for two or three seasons. I've had a lot of mentors who gave me so much, it's something I like doing. Why not give it a try?"
Asked to single out the three most memorable moments of his career, Immobile picked the Euro 2020 triumph alongside two moments closer to home.
"Winning the Euros. The Lazio-Brescia match, which was the toughest for me because I absolutely had to score to win the Golden Shoe and it was really tough emotionally. And I'd also include the run of Coppa Italia and Supercoppa wins with Lazio."
