UEFA has reportedly sent a letter to FIFA demanding an explanation of Gianni Infantino’s leadership. UEFA wants a response by 2 November. Infantino is president of FIFA, while UEFA governs the sport across Europe and runs its major club competitions. The published report does not explain which decisions or aspects of his leadership prompted the request. That leaves the substance of UEFA’s concerns unclear. A firm deadline gives the exchange the character of an official escalation rather than a casual query. The exchange also puts added strain on relations between the two football organizations.
