You can only buy one non eu player from outside italy per season. I've bought Lucio for 15 mil €, did a straight swap between Ljungberg and Davids. I sold Thuram to Liverpool for 11 mil, Zala for 5 mil and Iuliano for 6.5 mil to chelsea. I now have 9 mil € to spend, and I'm drawn to both Salih and Giuly.
My idea for next year is this:
GK Buffon
DL Zambrotta
DR Salihamidzic
DC Lucio
DC Hofland/Bonera/Samuel
ML Vicente/Robben/Reyes
MR Giuly/Joaquin
MC Ljungberg
MC Appiah
ST Tevez
ST Trezeguet
I'm gonna sell Montero, Del Piero and Tacchi after the first season, hopefully I'll have enough funds.
P.S. I've also secured the transfer of Mexes for next season for 4.5 mil.
