he said no sane club.
this is juve who spent money on expiring contract zakaria, expiring contract djalo. and 4th goalie.
We buy Zakaria for 11.35m, send him on loan to Chelsea for 3m, then sell him to Monaco for 20m
Basically we are getting 23m- 11.35 = 11.65m, with this money from Zakaria we can basically buy Tiago Djalo and pay for 4th goalie loan+ salary for 1 year (free Djalo and free 4th goalie)
Imagine if we can sell Djalo for 16m (which is his max value based on transfermarkt) after we loan him and he get attention from some clubs after this season. He is currently in 12m valuation. So if we can get lets just say 16m from him, then we can pay the obligation of that 4th goalie. Which is means free best GK of the season in Serie A
That is how Giuntoli cook these transactions while he earn commission from all of these transfer. You cant play Giuntoli's 4d chess, only 25 years FM veteran can see how these moves shaped out
And I just took all of this equation based on those players that you mentioning
