I'd also add that in Italy, Juve is still considered to have the refs in their pocket, having been the benefit of more than a few questionable decisions over the past two seasons. But, any way you look at it, it's impressive.
However, I feel Milan's run of 58 from '91-'93 is more impressive because of how much they were a regular factor deep in the Champions League then. They were widely considered the best team in the world then, nevermind just on the peninsula.
