Juventus coach Massimiliano Allegri has told his players that they must improve despite seeing them reach the last 16 of the Champions League.
The Italian champions earned the point that they needed to go through on Tuesday, drawing 0-0 at home with Group A winners Atletico Madrid.
However, Allegri believes that Juve need to assert themselves more when they are facing "big teams" such as Atletico.
"It's always complicated against Atletico, as they defend very well with tight lines, so it's not easy to find passes between the lines," he told Sky Sport Italia. "We didn't want to compromise our chances of qualifying and I thought it was thoroughly deserved.
"Of course we need to improve. Against these big clubs, there are times when you have to defend and protect yourself - something Atletico Madrid do for most of the game."
Juventus continue the defence of their Serie A title on Sunday when they host Sampdoria.
