Juventus assistant manager Angelo Alessio warned Paul Pogba that he has a lot to learn if he wants to be a success in Turin, despite the young midfielder's goal sealing victory over Bologna.
Saphir Taider pegged the Bianconeri back after Fabio Quagliarella had opened the scoring 10 minutes after the break, but Pogba struck late on to keep La Vecchia four points clear at the top of Serie A.
Second-placed Inter Milan will present a stern test to Juventus as the Turin outfit look to go 50 games unbeaten on Saturday night, with Alessio still unsure over his line-up for the crucial clash.
He told Gazzetta.it: "Pogba was fantastic and played a great game, but I have one criticism - he has to stay focused.
"After 20 minutes he became a bit distracted and that's not good.
"Knowing (suspended head coach Antonio) Conte as I do, if Paul doesn't tighten up that part of his game then he will not go far.
"Winning is never easy and today we had to wait right until the very end, even if we deserved to get there earlier.
"Bologna are a great team but they're not getting great results at the moment.
"Everyone played their role properly tonight, we felt the absence of (Claudio) Marchisio and (Arturo) Vidal, but (Emanuele) Giaccherini and Pogba were great.
"Who will line up against Inter on Saturday night? Today we are just enjoying the win, but we will start thinking about that tomorrow."
Bologna boss Stefano Pioli may have been on the sharp end of an incisive display from Pogba, but he still found time to praise the ex-Manchester United prodigy.
"Pogba is an incredible footballer, he has impressed me with his quality, physique and personality," Pioli told Raisport.
"He's strong now, he's no longer just a prospect."
The Parma-born tactician remains confident he can guide Bologna out of the bottom three and up the league table.
"I'm not stressed, I remain determined even though we're not getting results," he added. "This team has spirit and valour, we just need to start winning."
