Juventus striker Paulo Dybala says they weren't at their best for victory Palermo.

Juve won 4-1 on Friday night, with Dybala scoring twice.

"I think we've made a big step forward, but we didn't play very well," Dybala told Mediaset after the final whistle.

“In the first half we dropped too many passes, we were superficial and we can't allow that to happen.

“Against Porto we'll have to change our attitude and mentality, it won't be easy and we have to be focused for Wednesday's game."
