Inter Milan are interested in Franco Mastantuono. An Argentine news outlet has reported that Madrid are ready to send Mastantuono out on loan for next season and that the Spanish club do not want any buy option in a potential deal for the Argentina international winger because he is considered a key part of their long-term sporting project. Fabrizio Romano reported that Madrid are open to sending Mastantuono out on loan this summer with no buy option clause in a straight loan.

According to Spanish publication SPORT, Inter Milan will face competition from Tottenham Hotspur, Villarreal, Porto, Sporting CP, Benfica, Juventus, River Plate, and Rennes to sign Franco Mastantuono.

Franco Mastantuono's name was mentioned during a meeting in Madrid between the leadership of Inter Milan and Real Madrid. According to Mundo Deportivo, the names of Rodrygo, Endrick, and Franco Mastantuono were brought up after discussions about another player became complicated. Mastantuono joined Real Madrid in August 2025 and has a contract with the club until 2031.
