There is one team all of you seem to be forgetting about.
Fiorentina.
If you check the standings you will see that they are only 4 points behind us and 6 points behind 4th place. But there is one minor detail we forget when we count them out of the 4th spot battle: They hit amazing form. In the last two rounds, after they were eliminated from CL, they beat Napoli away (no-one else did it this year) and then they destroyed Genoa.
If you check their schedule you will see that it's very similar to ours.
1. Juve play Milan away, Fiorentina play Milan away
2. Juve play Catania away, Fiorentina play Catania away
3. Juve play Inter away, Fiorentina play Inter at home
4. Juve play Udinese away, Fiorentina play Udinese at home
5. Juve play Bari at home, Fiorentina play Bari away
6. Juve play Atalanta at home, Fiorentina play Atalanta away
7. Juve play Parma at home, Fiorentina play Parma away
The only differences are:
1. Juve play Napoli away---Fiorentina play Siena at home
2. Juve play Cagliari at home --- Fiorentina play Chievo at home
Apart from Milan and Inter, all Fiorentina's opponents are from the 11-20th place. Considering their and our form, I can easily imagine Fiorentina nullifying the 4 pts difference between us and eventually overtaking us and even Palermo.
If Prandelli manages to get the 4th place for the 5th season in a row, and especially if he does it this year when only 10-11 rounds before the end his team was 10th placed, I will have to retract most of what I said about him.
Maybe my fear isn't justified, but I see Fiorentina as our most dangerous rival for the 4th place.
