Real Madrid's summer signing of Franco Mastantuono was supposed to be a blockbuster—a teenage sensation arriving from River Plate with a reputation that had fans buzzing and expectations soaring. But so far, the young Argentine has struggled to find his footing at the Bernabeu this season, especially with tensions simmering behind the scenes in the dressing room.

Now, a Real Madrid legend who knows exactly what it's like to carry the weight of Argentina on his shoulders has stepped in with some perspective. Roberto Martinez—a man who netted 108 goals for Espanyol and won five La Liga titles with Los Blancos after making the same transatlantic leap—shared his thoughts ahead of tonight's clash between his two former clubs.

Speaking to Diario AS, the 79-year-old icon was measured but sympathetic toward Mastantuono, pointing to the unique pressures of adapting to a new country, league, and club culture at such a young age. "He's a great player, no doubt about it," Martinez said. "But he's being affected by his acclimatization. He's young. He needs chances to show what he's worth—that boy plays very good football."

When the conversation turned to whether a loan move might help unlock his potential, Martinez didn't dismiss the idea. "It's quite possible that would be right. He hasn't yet shown what he's capable of. It's a special case because we didn't think he was going to fail. After all, he came with a tremendous chance of being a star. In big teams, sometimes that weight affects how you play."

Finally, asked if Real Madrid need a major overhaul next summer, Martinez stopped short of calling for a revolution but stressed the need for evolution. "Football has changed a lot, and we have to prepare to stay in the fight at the top. Because that's Madrid," he concluded.
