So last time I posted this people pointed out a few things that should be revised, so I altered them. Specifically, I fixed the issue with the gross/net wage discrepancy between England and Italy, and also revised the transfer fees/wages to the most current figures I could find. I didn't include bonuses for any players. Of course many of these numbers aren't confirmed officially and reported by sources like Daily Mail/Tuttosport/Gazzetta/Metro or whichever other agencies report salaries and transfer fees when "officially" they haven't been disclosed or they are just rumours. That being said I tried to be conservative and pick the higher ones.
I also beefed it up a bit. Let me know if anyone thinks certain numbers should be altered/revised.
