Sarri's side have now won just two of their last seven matches, falling to defeat in three of those. With the title already in the bag, Juventus host Roma on the final day of the season, while Cagliari - previously winless in eight games - travel to Milan.
Juventus fall to a 2-0 defeat against Cagliari in their first game since being crowned champions. Gagliano converted from close range and Simeone scored from further out to give the hosts a two-goal half-time lead that they did well to protect, with Juve showing a lack of cutting edge in the final third.
