Juventus coach Max Allegri plans crunch talks with two of his new midfielders next week.

Allegri is unhappy with the form of Douglas Costa and Rodrigo Bentancur as Juve struggle to keep pace with Serie A leaders Napoli.

The Bianconeri coach believes the pair are capable of much more and will sit down with both players when they return from international duty to discuss their form.

Gazzetta dello Sport says Allegri will make it clear they cannot afford to cruise and must step up their intensity.

For his part, Douglas Costa has admitted he's struggled to adjust to Serie A's demands since his loan move from Bayern Munich.
