Juventus coach Ciro Ferrara is keen for fans not to put pressure on youngster Sebastian Giovinco.
"Giovinco did well (against Bordeaux). He is not and never will be Diego, but that is obvious," mused Ferrara.
"There is no such thing as a player identical to another and I don't like talking about those who didn't play, as it's not fair.
"In the past six years this team has adopted the 4-4-2 system, but we changed to a diamond midfield and have a different way of approaching the game.
"This naturally means there are movements and tactics that will take a while to gel perfectly."
