Uefa has escalated its feud with Fifa president Gianni Infantino, filing legal papers in the US that accuse him of "criminal mismanagement" over a shelved plan to sell stakes in competitions. The documents allege the World Cup was undervalued and the deal lacked transparency, referencing "cronies" and a history of corruption. Uefa seeks evidence for potential litigation in Switzerland, while Infantino denies wrongdoing, calling the claims "categorically untrue." Despite pressure from Uefa and others to step down, Infantino has gained support from the Saudi Arabian federation and continues his global tour, including a visit to Vietnam.

Uefa's move to prepare criminal proceedings marks a dramatic escalation in the ongoing civil war within football's governing bodies, with no sign of resolution as the U20 Women's World Cup approaches.
