BREAKING TWIST: Tensions rise at Old Trafford as manager Rúben Amorim reportedly issues a firm ultimatum — and the club wastes no time responding. Manchester United are now eyeing World Cup hero Dibu Martínez as a potential replacement for André Onana. A shake-up is coming, and no one’s seat is safe.

Chaos is quietly brewing behind the scenes at Old Trafford.

According to multiple reports, newly appointed manager Rúben Amorim has issued a firm ultimatum to the Manchester United board regarding the club’s defensive inconsistencies — and the spotlight has landed directly on goalkeeper André Onana.

Sources close to the situation describe Amorim as “deeply concerned” about the lack of reliability between the posts. Despite a handful of strong performances, Onana’s inconsistency — particularly in high-pressure moments — has reportedly tested the patience of the coaching staff.

And now, United may be preparing for a seismic shift.

The club is actively exploring a shock move for Argentina’s World Cup hero, Emiliano ‘Dibu’ Martínez.

The Aston Villa star — known for his commanding presence, shot-stopping brilliance, and penalty box dominance — is being considered as a direct replacement for Onana if performances don’t drastically improve before the end of preseason.

“Amorim didn’t come to Old Trafford to protect egos,” a source close to Carrington said. “He wants warriors — not passengers.”

Martínez, who played a critical role in Argentina’s 2022 World Cup triumph, is also admired for his vocal leadership — something the United dressing room has been accused of lacking. Early conversations are said to have taken place between intermediaries, though no formal offer has yet been made.

Inside the locker room, the mood is shifting. Amorim’s arrival was supposed to mark a tactical evolution — but it’s quickly becoming clear that this is also a culture reset. One where no name, no reputation, and no price tag guarantees protection.

Onana, for his part, has remained quiet. But those around the club say he’s aware of the pressure — and that this preseason could define not just his role, but his future at United.

The message is clear: compete or be replaced.

With less than a month before the Premier League kicks off, expect drama. Expect decisions.

And above all — expect a manager unafraid to light the match.

A shake-up is coming at Old Trafford.

And no one’s seat is safe.
