Real Madrid begins a crucial week in Europe with worrying news. Franco Mastantuono, one of the club’s brightest young talents, has been diagnosed with pubalgia after undergoing medical tests at Valdebebas on Monday. The 18-year-old midfielder, who has quickly become a key piece in Xabi Alonso’s system, now faces an indefinite spell on the sidelines.

Official Diagnosis

In an official statement, the club confirmed the extent of the injury:

“Following the tests carried out today on our player Franco Mastantuono by Real Madrid’s Medical Services, he has been diagnosed with pubalgia. Pending evolution.”

The statement does not specify an exact recovery timeline, but pubalgia is notoriously complex. Depending on severity, it can keep players out anywhere from a few weeks to several months — a serious blow for Xabi Alonso, who now loses an important attacking option during a pivotal stretch of the season.

A Setback for Xabi Alonso

Mastantuono had become one of the breakout stars of Madrid’s campaign. Despite his youth, he had earned a regular spot in the starting XI thanks to his pace, vision, and relentless drive. In recent matches, however, his physical drop-off had been noticeable — something this diagnosis now explains.

With the Champions League trip to Anfield fast approaching, Alonso’s squad depth will be tested once again. The Argentine joins a growing list of absentees, limiting rotation options as Madrid battles on multiple fronts.

What Is Pubalgia?

Often referred to as a sports hernia, pubalgia occurs due to an imbalance or overload between the abdominal and adductor muscles. For footballers, it causes pain when sprinting, striking the ball, or twisting the torso — movements essential to their game.

If not properly treated with rest and physiotherapy, it can become a chronic issue, which is why Madrid’s medical team has opted for a cautious approach. Mastantuono will remain under close observation, with his recovery dictated by how his body responds over the coming weeks.
