1-Benzema has signed a contract extension until 2019, rumors are he almost doubled his wage, from 4.5M Euro to 8M.
2-Taider (owned 100% by Inter) moved to Southampton on loan with an option to buy for 9M Euro, Daniel Pablo Osvaldo moved to the opposite direction with an option to buy for 7m Euro. Osvaldo also took a 50% paycut, he will earn 2M Euro instead of the 3.2M Euro (net wages) he used to get from Southampton, with a 200k bonus if he scores 20 goals (
source).
3-Gary Medel is on his way to Milan for a medical with Inter, he will earn 1.8M Euro (net), Inter will pay Cardiff 8M Euro and an additional 1M if they qualify for the CL next season.
4-Adrien Rabiot and Rolando (Porto) should both be set to "set to leave on end of contract", both are forcing moves, will not stay at their clubs, and are on the final year of their contracts, Rolando might even buy his way out of his contract.
5-Juventus own 100% of Isla (remove Udinese's 50%) and have loaned him to QPR for 1M Euro with option to buy for another 10M.
6-Juve bought Romulo as a replacement, he is owned 100% by Verona, loaned for 1M Euro with a non-optional obligation to buy for 6M euro if he plays 60% of Juve's matches (essentially like a loan with a future transfer), his salary will be 1.5M Euro (net), you should also remove his Italy cap, he hasn't played for Italy and could still decide to play for Brazil if he wants to (unlikely).
7-Shouldn't Simone Zaza be with Sassuolo, instead of at Juventus with a future transfer, since he played with Sassuolo this season?
8-Vidic has obtained a British passport, this is an important change, as it doesn't take a non-EU slot, his contract with Inter will see his salary reduced to 3M after tax
9-M'Vila's wage should be 2M after tax, he took a huge pay cut to join Inter, also the fee to make the move permanent is 9M Euro (not 10).
10-Do you have a way of implementing buy-back release clauses for Morata and Casemiro for Real Madrid, Duncan and Longo for Inter?
