It was clear to anyone looking at the numbers and the salary cap imposed by La Liga, that the optimism in him re-signing was 100% dependent on an exemption being provided by La Liga. There was simply no other way without shifting out all of Griezman, Dembele, Coutinho, Umtitti and Pjanic. And even that may not have been enough. La Liga haven't flinched, and here we are. Players have to be registered by the end of the month to be eligible for the season and by September 2nd to be eligible for the CL. If Barca were going to pull a move, it was now or never.
I have zero doubt that this is a move to invite pressure on La Liga, but one should also consider that this is a way for the two to part company without either taking the blame. Which is probably a unique opportunity. It'll be interesting to see what happens, because like most of you, I don't think is definitively decided yet. What is for certain is that between this, the ESL, and the CVC deal, Spanish football is in civil war.
