Here's a fre tip from me: IMO the two friendly games tommorrow (Valencia-Lazio and Barcelona-Parma) are pretty safe bets.
Valencia has gotten a lot stronger over the summer, while Lazio has lost all it's best players, and to top it off neither Inzaghi nor Muzzi will play. Also, Barcelona looks good to beat Parma, they've got a fantastic team, while parma have also sold off many of their best players, adn those they havent are playing in the Olympics, Bonera, Gilardino and Barone.
So, my advice is to bet on Valencia and Barcelona.
