A 5-1 win at Arezzo was enough for the Turin giants with Alessandro Del Piero and Giorgio Chiellini scoring two apiece and David Trezeguet adding another.

Juve coach Didier Deschamps, installed last summer after their relegation, said: "It's a great achievement and we all worked together for it. We are joyful and the players are celebrating with good reason."

Juve's path back to the top flight was smoothed after their points deduction was cut to just nine points.

Originally prosecutors at the Italian Football Federation had wanted to demote them to Serie C1.

Genoa and Napoli look likely to join them in Serie A next season.
