If I’m following this right, he doesn’t really want to leave Barca but he will as long as he gets his back wages. He doesn’t especially want to come to us but he will if the deal is right and because he likes ETH (if other clubs were willing and able he might prefer them but no other clubs are all that interested). Probably feels he won’t get his money even if he stays.
Barca want to make everyone involved in this look like mugs or worse and are pretty keen to shaft FDJ from all angles, blithely making new signings while blaming FDJ for bringing the club to its knees by having the temerity to claim what he is owed (no more). Probably they’d rather burn their own stadium down than lose face (or fulfill their obligations).
We want FDJ but we won’t accept a hosing. Probably we don’t have a realistic alternative and we are pressing on in the hope that the assurances we’ve been given will actually hold up (they often don’t).
Looks like if this deal doesn’t happen, everyone loses. At the same time, I can’t say it looks too rosy for anyone if the deal does happen.
