Former Juventus coach Giovanni Trapattoni has defended the work of Massimiliano Allegri.
Allegri is under pressure as Juve stutter this season.
"You can only make wine with the grapes you have available," Il Trap told Tuttosport.
"You can't always be beautiful.
"Max is right, it's hard to win Championships by playing well throughout. The Coach can't always guarantee a spectacle.
"The recipe for success is to change from time-to-time, like a chameleon to reach your goal."
