Like said, at least Sanchez needs to be bought out with that 4m€ release clause. That's 6m gross. So subtracting that from his current gross salary of 10m, we're gonna save 4m€ gross. Same has been said about Vidal, that he has an option in his deal and similar kind of buyout clause but let's see. If not, we gonna save his gross salary which is less than 10m€. Dzeko has still one year left of his deal 5m€ + bonuses so that's 9m€ gross + bonus. We can't just wipe that money out, we need to pay him if we want to get rid of him.
So it's not like we can clear 35m€ gross salaries next summer by removing these three players.
Lautaro makes 6.2m€, no growth decree so that's over 11.5m€. Brozovic 6.5m€, no growth decree so that's 12m€. Dzeko like said 9m€. Actually Lautaro and Brozovic might make more than Vidal and Sanchez because of the growth decree. Of course the difference is not as much since they had salary before the raise too but the point is how much salaries we need to pay. And it's a lot.
