Yes, I know that the defeat to Viola hurts but there are reasons more then prestige and keeping milan at bay to beat Juve on Sunday.
First of all, Fiorentina has won all their hoem games except the Juve game in which they deserved to win, but were unlucky.
Second Juve only gained one point on you. -8 or -9 makes hardly any difference. Hell, it would have been worse if you had drawn and Juve had won.
If Inter wins they will be at -6 with 13 games to go. And with Juve having the most difficult schedule in the last 9 games or so(true, most of them at home, but if Parma could have done it...) the future does not look so bleak.
Juve is definitely off-form. All that Inter needs is for the attackers to find the goalscoring touch again. Remeber before the derby? Adriano was in a bit of a downer but then tore Milan to pieces. So forget about last night and support the team on Sunday night!
