Diego expects to start the season a Juventus player.
The Brazil midfielder has struggled to find a place in new coach Gigi del Neri's playing system so far this preseason.
"As everyone knows, my agent is my father," Diego said. "If other agents are offering me to other teams this does not reflect the reality of the facts.
"We are ready to have a great season of football. I am with Juventus and I won't accept any extra interference with my play.
"I am concentrating with my team and I am certain of being able to give a lot of happiness to the Juventus fans."
