Can they really ever get more than 80m for this guy? Even an established PL player, Brazil starter like Raphinha went for 65m.
No, unlikely. But the real value of keeping him would be to win the league and playing in the CL the year after. Right now we still only have one direct CL spot so 2nd place could miss out. And no we won't walk the league even with Antony. Season after most likely we have two direct CL spots which obviously matters a ton.
Also getting out of the group stage means a lot of income. And with Antony our chances of this will just improve a lot and is worth a lot.
Also Sao Paulo get 20% of profit.
So even though his sale value will most likely drop, his overall value might be worth it by keeping him.
So the decision between keeping him for another season or selling him now for 80m is not a no brainer decision.
Also we love to watch him play, and it is fun watching your team play good football.
I am really indifferent. The prices quoted can't really not sell him for that amount but also really love it to see him one more year and then move on.
Of course worst case scenario is injuries but that is a risk worth taking.
Him going on strike seems pointless anyway. He has a long contract left and he would jeopardize his world cup spot by not playing now so that wouldn't really benefit him.
