Top 10 most expensive Serie A signings of January transfer window
Lorenzo Lucca, Giacomo Raspadori and Robinio Vaz were among the most expensive Serie A signings during the 2026 January transfer window, which saw the Italian top-flight sides spend a total of €243.49m over the last 31 days.
The January transfer deadline struck at 19.00 GMT on Monday evening. Milan failed to get a deal over the line for Jean-Philippe Mateta, but there was still plenty of action on the final day of the window, including Juventus’s signing of Emil Holm from Bologna, Joao Mario moving in the opposite direction, and Roma’s acquisition of Bryan Zaragoza from Bayern Munich.
The full month brought several new additions, including new Roma striker Donyell Malen, Napoli’s acquisition of Giovane and the return of Giacomo Raspadori from Atletico Madrid.
Technically, Lorenzo Lucca, who left Napoli to join Nottingham Forest in January, was the most expensive Serie A signing this month. That is because the Italy international was still on loan with an option to buy at Napoli, and the Partenopei had to exercise that option to buy clause from Udinese before sending him to the Premier League.
Coming in at joint-second are Giacomo Raspadori, who joined Atalanta after six months in LaLiga with Atletico Madrid, and Robinio Vaz, who joined Roma in a permanent deal from Olympique de Marseille.
Below are the top 10 most expensive permanent signings from the 2026 January transfer window in Serie A.
