The whole argument of 'others were cheating as well, so we're innocent' doesn't make sense. Best outcome is Inter get dragged down as well. But Juve will always have Calciopoli as part of their history and it's effects on the clubs reputation will take years of prolonged success to get away from.
Players like Aguero won't run to a falling Italian league to play for a convicted corrupted team. Fans may be able to look past this but Aguero has no affection or loyalty for Juve. I get the feeling he'd come if no one else came forward but other clubs would be preferable.
