Claudio Marchisio admits they weren't at their best for a 3-1 win over AC Milan.
Marchisio hit the post during the victory.
"I was unlucky as I could've scored there, but what counts is the three points," Marchisio told Sky Sport Italia.
"It was not an easy game. It's true we managed to get right back in front after the equaliser, but in the second half we didn't come out with the right attitude and were under pressure. It wasn't a proper Juve performance.
"After the third goal we controlled the game again, but at the moment we are struggling to keep our concentration for the whole 90 minutes."
