Relegation-threatened Cagliari could benefit from Juventus attention lying elsewhere when the two sides meet in Turin on Saturday.
The 18th-placed Cagliari gave their unlikely hopes of Serie A survival a boost with a thumping 4-0 win over rock-bottom Parma on Monday that saw them close within six points of safety.
Just four matches remain in the season but Cagliari have Atalanta, who sit 17th, in their sights, and will hope Juve - crowned Serie A champions for a fourth season in a row last week - rest and rotate their squad.
Juve's focus will be firmly on the second leg of their UEFA Champions League semi-final on Wednesday. Massimiliano Allegri's men secured a well-earned 2-1 home win over Real Madrid in the opener earlier this week.
"The boys have become aware of their capabilities," Festa told the club's official website.
"[Parma] was a good performance, a new step…to feed hope. Surely we will continue to play with that desire and commitment until the end."
After a winless run of 11 matches, which included nine defeats, Cagliari have won two of their last three, with a tremendous 3-1 success at Fiorentina last month raising spirits.
Juve's home end will be made up of 9,500 school children, though, after the stand was shut as punishment for clashes with Torino fans in April. The stand has been re-opened Italian Football Federation accepted Juve's proposal to put school kids in the 'Curva' instead.
If he starts, Serie A top-scorer Carlos Tevez could continue his superb run of form. Tevez, who won and scored a second-half penalty against Real Madrid, has scored five times in his last six league games.
