This report sounds highly sensationalized and unlikely to be true. Real Madrid does not have a single “owner” who makes such direct ultimatums. The club is owned by its socios (members) and is run by president Florentino Pérez, who has historically been strategic in his decision-making rather than issuing public threats to a manager like Carlo Ancelotti—one of the most successful coaches in Madrid’s history.
That said, if there is pressure regarding a 20-year-old player, the most likely candidates would be Arda Güler or possibly Jude Bellingham (who already plays regularly). Güler has struggled for minutes due to injuries and Madrid’s stacked midfield, so speculation could be centered around him.
However, Ancelotti is not the type of coach to be dictated to in this manner, and Pérez typically handles such matters discreetly. If this were true, it would be an unprecedented move in Real Madrid’s history. I’d recommend checking trusted sources like Marca, AS, Fabrizio Romano, or The Athletic to verify if there’s any legitimacy to these claims.
