Juventus coach Max Allegri is wary facing a "cunning" Villarreal on Tuesday night.
The Champions League round 16 first-leg clash will be held in Spain.
Asked about Villarreal's determination, Allegri said: “Very. Because the coach is clever and cunning. We need a serious match, a Champions League match to be played with great calmness and focus.
"We'll have to be good at managing the ball, which is something we'll have to improve on."
The game will be Dusan Vlahovic's Champions League debut.
“He's a youngster who has zero international experience, he's making his debut tomorrow and so we need to help him, he'll help the team. It's a path of growth for him and for the whole team," added Allegri.
