That is a tough one. I would absolutely hate it if they won it i guess. Here's what i think about:
Roma: Garcia, Totti and their whole "er are victims, refs are against us"-attitude tells me no. I do respect Palotta though, he has visions for Calcio, and we need strong competitors to make the league more attractive, and Roma could be one of the clubs who makes the cut long term.
So does Napoli, but i have no respect for De Laurentiis at all. Furthermore, their attitude and mentality is even worse than Romas i guess, and guys like Higuain and Callejon makes me feel the same way as Totti and co. I do have massive respect for Sarri though, seems to be a great coach, a down to earth respectfull guy who just loves his club and loves what he does. I can surely owe him some succes.
I'd rather see Lazio or Fiorentina win it to be honest. I also admire Sousa and Pioli a lot. They seem classy, and are potential future Juve coaches in my eyes. I don't respect Lotito, but i actually think Lazio has a group of players more likeable than the others at the moment. Maybe it's just because we always beat them i feel this way... I also really respect some of Fiorentinas players despite the whole rivalry-thing going on between the clubs. Their president is a douchebag though (how come i hate all the presidents?) and i have no respect for him at all. Guys like Rossi, Valero, Rodriguez are likeable to me, and they have some exciting young players and play a branch of football i really enjoy watching.
To be honest i am not sure i really care so much though. I really care about us winning, but that's about it. I could live with a top 3 finish this season as long as we seem to be going in the right direction and will be back in bussiness next season. CL is a bonus this year, i expect nothing but qualifying from groups, from there on it depends on the draw etc.
