Paulo Dybala suffered an ankle injury in Saturday's win by Juventus at Pescara.

Massimiliano Allegri is optimistic Dybala will be available for the second leg of Juve's Champions League tie against Barcelona. Dybala scored two goals in the first leg.

"Dybala took a blow, there is a distortion," Allegri said. "But, with four days to recuperate before Barcelona, you have to be optimistic."
