I don't think Vieira did bad with Juve, he scored his highest amount of goals with Juve in any given season. It's harsh to blame him for the CL's failure, I would blame Capello for that, he hasn't taken any team beyond the quarters for over a decade. Vieira also had an excellent world cup that year too. I think he lost it at his time for inter, I kinda feel sorry for him to be honest. He came to win the CL, yet he was released by Inter in Jauary of the season they just won the CL
