I don't think we are waiting on the Nike deal to sign him, if we sign him it will be through other means.
I read a few weeks ago, they see the Nike renewal happening in the medium term, their is no rush on Nikes part to give us all that extra money, when they have 2-3 years left on the current contract, they will renew, but it's unlikely to be a days/weeks thing
We probably already have the money to sign him like we did with Olmo, at that points it's just moving pieces around in the squad to get everyone registered and maybe a cash injection from an unknown source.
