It will be really difficult to get tickets for the Juve end, I would assume most if not all tickets will go to the Ultras.
I have had problems in the past trying to get tickets in the Juve end at Champions League games in Glasgow. My family friend was the Celtic physio and not even he could get me tickets in the Juve end when they played Celtic a few seasons ago. He actually got me tickets right next to the Juve end and I managed to persuade a steward to let me cross the barrier to sit in an empty seat with the Juve fans. (
Im mentioning this because having been at the game I know that I would not have been able to control myself when Del Piero's freekick went in, if I was with the Celtic fans!
But I guess wanting tickets with the Juve fans is just being picky and it would be brilliant to sit anywhere in the stadium!
Out of interest has anybody tried getting tickets from here in the past:
