I am pretty sure Potter knew he was going well before the event happened. Fabrizio Romano probably knew in the summer :).
Do you think those contracts for all those people to transfer were prepared in a little over 24 hours?
As we're all coming up with suggestions for what may or may not be going on. Perhaps his purchase was some sort of 'peace' deal after the other shenanigans that went on between us and Chelsea. Perhaps the player didn't want the move to us in the first place.
