They likely won't get docked points given that there would be a massive legal case on the scale of Italian football if that were to happen. If anything, they'll be docked points for the start of the next season. I don't think there's a realistic way that they can get through the full legal process in that short an amount of time.
Tough thing about Tevez. United don't need him because we have Rooney in that position and Rossi backing up Rooney, however we don't want any of the other big four to get him, either... so it's a tough call on how that will end up. Absolutely fantastic player, though.
