Cagliari midfielder Radja Nainggolan is staying calm over renewed transfer speculation.

The Belgium international is being linked with Juventus and Manchester City.

"I have an excellent relationship with my agent, he's like a father for me and I have great trust in him," the 24-year-old told Tutto Cagliari.

"Now is not the time to discuss my future though as there are still four games left and I want to end the season well. Then we'll see what happens."
