Diego has cast doubt on his future at Juventus.
The midfielder could be sold this summer as Juventus are planning on changing their system to a 4-4-2, which doesn't suit his playing style.
Diego told Tuttosport: "I am well here. I am calm."
When asked if he expects there to be problems regarding his place at Juventus, he replied: "I don't believe so, but I don't know."
