I didn't go through the entire thread, so forgive me if these have already been updated:

3 year contract €1.3M per year), Ruben Botta (
5 year contract €1M per year), Diego Laxalt (Has an Italian passport,

3 year contract, his idol is Iniesta), Axel Bakayoko (

Please add to Francesco Bardi's favorite personnel (idols) Buffon, Peruzzi, Handanovic, Marchetti.
Also, unfortunately, Inter are obligated to purchase Gargano, Mudingayi and Silvestre at the end of the season, not sure if full-ownership or co-ownership, but they are definitely not going back to their former clubs.
There are no contract clauses, because these are illegal in Italy, but there is a gentleman agreement for each of these.
