“Dybala got his first goal of the season, I am happy for him and for the team. It was important to get our first Champions League win of the season," Allegri told Mediaset Premium.
“The side took the right approach. We made some mistakes in the second half, when we could've played better, and still need to improve. We need to play cleaner.
“We are working, we've only been together for 40 days and there are players who arrived after the Euros. It takes time to get the players into a unit and we've had a fairly decent start, all told."
Allegri continued: “I repeat it, as the real challenge for Juventus now is to avoid complacency and the illusion that we'll win each game easily. As well as improving our overall performance, Juventus must bring home results, keep our feet on the ground and not lose sight of our objectives.
“Don't forget that achievements are all the sweeter when you must struggle to reach them. We ran a big risk at Palermo on Saturday and struggled to get that win."
