Juve are seven points adrift of the Champions League qualifying spots.
"It really is a shame. Conceding the equaliser with the last kick of the game, when we were 2-0 up with 10 minutes to go, is not easy to swallow," said the defender.
"Our disappointment is even worse considering the importance three points would've had with the other results of the weekend.
"There are still head-to-head challenges and a win would've put us back in the running, even if fourth place is increasingly difficult to achieve.
"To those who ask what our objectives are, I can certainly ply that what we owe to ourselves, the club and above all the fans is to face each game with the utmost determination, trying to honour the shirt we wear. Unfortunately, the rest no longer depends on us."
