Juventus director Maurizio Arrivabene has admitted frustration with Paulo Dybala and Matthijs de Ligt over new contract talks.

Arrivabene was speaking before victory over Cagliari on Tuesday night.

He said, “I am accustomed to being a plain-speaker. Nowadays, many players have more loyalty to their agents than they do to the club shirt.

“Dybala is the Juventus Number 10 and De Ligt is a great defender. They have to do their jobs, we do ours. But there is a good rapport.

“It's very easy to talk about how much you care for the club colours, but you need to prove it on the pitch. And we want them to prove it."

Arrivabene continued: “Dybala had a lot of problems lately, but when he did play, he did well. He is an important player for Juventus.

“De Ligt's performances are there for all to see. We have a good rapport, when the moment comes, we will speak to them, just as we do to other players. We don't make any differences between them."
