Juventus won its second straight Serie A title on Sunday, beating Reggina 2-0 to finish three points ahead of second-place AC Milan.
David Trezeguet scored a first-half goal and captain Alessandro Del Piero added another in the last minute of play to spark the celebrations.
Juventus clinched its 29th "Scudetto" with 91 points from 38 matches.
But reports in Italy suggested that the Turin club, whose entire board resigned on Thursday after the team was linked to a refereeing scandal, may be stripped of the title if fraud is proven.
Luciano Moggi, whose wiretapped conversations touched off the scandal engulfing Italian soccer, announced he was resigning as Juventus general director.
Moggi, who was in Bari to celebrate the title, suggested he was retiring from soccer for good.
AC Milan beat AS Roma 2-1 at San Siro to finish second. Brazilians Kaka and Marcio Amoroso converted penalty kicks to give the team 88 points.
Juventus' title never was at risk after Trezeguet headed in the opening goal in the 23rd minute at the neutral field in Bari because Reggina was banned from playing at home.
The France striker scored his 23rd goal of the season after a save by Reggina goalkeeper Ivan Pelizzoli.
After Zlatan Ibrahimovic missed two scoring chances with heel and bicycle kick attempts, it was up to Del Piero, fielded as substitute in the 70th, to seal Juventus' victory.
Shortly after the match, hundreds of Juventus fans raided the field to celebrate the title. Many waved Italian flags with the colors of the "Scudetto."
In Milan, Kaka converted a fifth-minute penalty after Alberto Gilardino was fouled close to the net.
Roma defender Philippe Mexes equalized with a diving header in the 34th as Milan goalkeeper Dida reacted slowly.
Amoroso, seldom fielded since his arrival in January, gave Milan a last-minute victory by ring from the penalty spot after Cesare Bovo pulled Gilardino's jersey as the striker was about to score.
Bovo got a red card.
