Juventus have a good past record against Fiorentina. Juventus have defeated Fiorentina in their last two matches. So if they perform carefully in today's match and if the forward players play well, Juventus has a chance to win. Even so, I wouldn't risk betting on Juventus.
There is 4 points gap to Bologna, and Juventus's chance qualify is still remain big enough as long as it will take three points from all of its remaining games but im still holding a miracle to happen and old lady missed some points. There are still about 7 matches left for juventus and Allegri's main goal is to ensure his club plays in the UCL next season but this can also become the main consideration to determine his fate on juventus. Even though Allegri may be fired soon, it is now his responsibility to ensure that this happens.
Juventus still has a small chance of qualifying for the UCL next season. I hope Allegri will be kicked by the club at the end of season considering how bad his impact to the club. Juventus won narrowly against Fiorentina. It was not a particularly impressive result given Fiorentina's poor track record.
