Werder Bremen's Diego has signed for Juventus in a €25m deal, according to the midfielder's agent.
Giacomo Petralito claims the 24-year-old Brazil international has agreed a five-year contract with the Italian giants and will complete the transfer at the end of the season.
Diego has been an integral part of Uefa Cup finalists Werder's side since arriving from Porto in 2006 and he has been linked with Bayern Munich in the past.
But the player's representative, Petralito, claims his client has opted to leave Germany in order to make a big-money move to Serie A.
Petralito told Kicker: "Diego has signed for Juventus. Everything happened last Wednesday."
Diego, who is suspended for the Uefa Cup final against Shakhtar Donetsk, has scored 33 goals in 87 matches. He has also won 38 caps for Brazil and scored seven times.
