Lazio have moved to secure the future of one of the biggest surprises of their campaign, rewarding the 23-year-old right-back for his performances with a new long-term agreement. The defender has made an impressive transition into the first team after previous loan spells with Juve Stabia and Cremonese, becoming a regular in Gattuso's side.
The club confirmed the extension in an official statement, announcing that Floriani Mussolini will remain at the Stadio Olimpico until June 30, 2031.
The player was quick to express his pride at committing his future to the Biancocelesti.
“Renewing with these colours is a source of great pride for me. It is an extra motivation to always give my best. Forza Lazio!” he said.
The new agreement represents a significant improvement on the terms of his previous contract. Floriani Mussolini had reportedly been earning around €150,000 per season on a deal reflecting his status as a Primavera player. His new salary is understood to be approximately €600,000 annually, with further gradual increases included in the agreement.
The improvement reflects the speed of his progress and the importance he has acquired within the first-team squad. Having returned from his loan experiences, he has taken advantage of his opportunity in Rome and established himself as Gattuso's preferred option on the right side of defence.
Lazio's decision also has a transfer-market dimension. According to reports, Inter had been monitoring the defender's development, prompting the Biancocelesti to act before interest from elsewhere could develop into a more concrete threat.
The renewal is part of the club's wider effort to protect the players who have contributed to an unexpectedly strong start to the season. Lazio have emerged as one of the early pace-setters in Serie A, and Floriani Mussolini's performances have made him one of the more encouraging developments in the squad.
His journey to the first team has included spells away from the capital, with loan moves to Juve Stabia and Cremonese providing valuable experience before he returned to compete for a place in Gattuso's plans.
The new contract is recognition of that progress, while also giving the defender a clear opportunity to establish himself as a long-term part of the club's project. If his performances continue at the same level, the improved terms may not be the final word on his contractual situation.
For now, Lazio have secured his commitment until 2031 and made clear that they see him as an important part of their future.
