Werder Bremen forward Diego revealed his interest to move to Juventus but believes their bosses must negotiate with their German counterparts. “The Bianconeri directors should know that I am happy at Bremen and that I won't declare war on the club. “Juve must talk directly to Werder and if the two sides can come to an arrangement then there will be no obstacle," said the Brazilian forward. The 22-year old player has been in a terrific form with Bremen since 2006 and has attracted the interest of many top European sides like Inter Milan and Real Madrid. Diego is under contract until 2011 but is expected to leave the Bundesliga next summer.
