Juventus coach Max Allegri has called out Adrien Rabiot ahead of their Champions League clash with Chelsea.

Rabiot, 26, has flattered to deceive since switching from Paris to Turin on a free transfer two years ago, scoring just six times in 89 appearances for the Old Lady.

"Rabiot is available, his ankle is fine, so he'll be available," Allegri said. "If a big club like Juve chose these players there is a reason, the mentality makes the difference.

"They must be very determined in attending the training sessions, scoring, defending, these elements make the difference. How many good technical players haven't been able to explode in their careers?

"If I was Rabiot I'd be very angry with myself, how many goals has he scored in two years here? Ten? It's not acceptable, if I were him, I'd be very upset.

"He needs to improve all these things to get really better and I am sure he'll be able to do it this year."
