But seriously what I really don't get is Juventini not liking Del Piero, or even worse insulting him. One would understand non juventini hating Del Piero since they have more than 200 reasons for them to hate him

(and counting).
But juventini, what do you want more??
Someone to represent the club at best in ocassions out side the field, I don't think you can find a better person.
Someone who is a leader and idol for yongster to look up to
The Captain of your team, the team you supposingly support.
Has given all to the club for more than 13 years.
Your club top scorer of all time and he is still scoring.
Although he is 32 but he is still performing great even better than most youngster and literally is saving the club in many games with his brilliance.
A leader on the pitch. Gives moral support to all players.
Led your team to ALOT of victories in the past and still is leading the team to victories today.
Did not abandon the team when it got relegated. First one to come out saying I will stay with the club.
Took the crap from Capello and kept quiet to keep the squad united and save Juventus' pride.
All players look upto him whether young or experienced.
Has never let the team down.
Always respects the fans (yes that is you).
Seriously talented and is not a show off like ibra, uses the talent when needed.
Best free kick taker (in my opinion and in yours he can't be less than one of the best FK taker)
Best PK taker (my opinion and same as the above)
One of the best assitant striker in the world if not the best.
One of the best finishers in the world..
He keeps on scoring no matter what the team he is facing.
Not selfish.
Never speaks about himself. Always speaks about his team-mates and their effort.
He is so spirited and gives spirit to others. He can take the team from the lowest morals possible to the highest and we've seen it in many games, either by encouraging them or by just showing them a glipse of his brilliance.
And the list goes on..
So what do you want more to give him the respect he deseve let alone love him??
