Milan will win the rest of the matches I am afraid, I wish I can be positive for the Lazio match, If we escape that with a draw, that would be something. not the we can't beat them, but you know the current situation.
2 wins and 2 draw is enough, or a 3 win is enough too..
Juve - Lazio = 0-0
Siena - Juve = 0-1
Juve - Palermo = 1-0 or a draw!
Reggina - Juve = 1-2
we win the scudetto with 3 points, or with 1 point in case we draw with Palermo.
