Juventus coach Massimiliano Allegri has jumped to the defence of Hernanes.
The Brazilian was flat for defeat to Napoli.
“He did well against Manchester City, but with Napoli he was disintegrated. He has great technique," said Allegri.
"The 3-5-2 is not a consolidated system for this team, it is a new tactic and that means it takes time. There are 10 new players we have to explain it to from scratch."
