Mastantuono's talent didn't go unnoticed in Europe. Barcelona, Real Madrid, Manchester City, Arsenal, Chelsea, Paris Saint-Germain, and Manchester United have already expressed interest in him, with the latter showing more concrete intentions in recent days. Amid the growing interest, in April 2024, River decided to update his release clause, setting it at 45 million euros, with the possibility of extending it to 50 at the close of the transfer market.
His opinion on Gallardo
Supported by his experience, he also allowed himself to opine on the club's most influential coach. "For me, Gallardo is one of the best coaches in the world. It's true that Argentina is not the same as Europe, but he could easily be among the top five," he assured about Napoleon. He added: "I have no doubts, for me, he's the best in River's history."
Despite his current admiration, he confessed that during his time as a player, he didn't imagine that destiny for Gallardo: "I didn't see him as a coach." "He always had an amazing personality, and that character allowed him to build his career," he concluded.
