The Slovakia international admitted he felt the Serie A leaders were slightly fortunate to run out 2-0 winners in Turin and that a defensive error for Martin Caceres' goal cost them at least a point.
"Juve had a lot of the ball but never looked dangerous," he told Tuttosport.
"Unfortunately we left Caceres alone at the corner, and we were punished."
Walter Mazzari's team remain second in the table despite the loss, and Hamsik feels that they must take their disappointment out on their next opponents after failing to take the chance to move to the summit of the league.
He added: "This defeat will give us the right sort of anger for the next games. We start next weekend against Chievo, and that will be important.
"We then go to Bergame [to play Atalanta] and that will also be tricky.
“We have to work hard.”
