Fabio Cannavaro was barracked by Juventus Ultras at training yesterday in Pinzolo.
Over 5,000 fans attended the training session, which included about 30 members of a Juve Ultras group which continually jeered Cannavaro as he went through his drills.
There remains a fringe element of Juve's fans that are unhappy with Cannavaro's return to the club after he quit them following relegation three years ago.
