Toney was officially charged by the FA in November 2022 and then subsequent charges were levelled in December of that year. He was officially banned in May 2023. Not entirely similar, I appreciate, but it gives an inkling of how slowly the wheels turn.
With the international nature of the Paqueta case, it may take even longer for things to come to a head, so I’d be surprised if he’s clear to move in the winter window. Indeed, my concern would be that the cloud might still not have lifted by next summer. That would make planning extremely difficult.
