Perhaps they are waiting until they have dealt with all the requests so they can release a proper figure, rather than one that is out of date before it is even published
well Sporting published a different version of that one. Anyway it seems verbal rather than a change in the contract, so the contract he signed is still there. I am sure both sides will compromise in the end.
But it’s a two way street. Buying clubs want the cheapest deal, selling clubs want to get as much as possible. Players want security until it suits them.
