In the books of football clubs when the team sells a player the team can get a gain on sale. This is different from cash profit. It is calculated by taking the amount of money received less the player's estimated value (not what we paid for him).
It is hard to tell because it may not be a very good translation but it is possible that this is what the 75m relates to.
Isco is great but signing Isco would mean 4-3-1-2 / diamond which means Khedira Marchisio Pjanic Isco - Its not bad I guess but the thing is I see Khedira and Marchisio getting injured a lot and we might be in need to get another mid if we play with Isco!
Kovacic - He is a high potential player but I would say no to any deal that isnt a loan deal!
