Diego is delighted to have officially signed with Juventus.
The Brazilian put pen to paper on a £24.5m transfer from Werder Bremen yesterday after undergoing a medical and spoke to Sky Sport Italia television.
"I chose Juve because they are one of the best teams in the world and we have been discussing this move for two and a half years now," said the man who took Werder Bremen to the UEFA Cup Final.
"I always had a soft spot for Juventus and it was the best option for me."
He had also been linked with other clubs, above all Bayern Munich and Inter, but opted for the Bianconeri.
"Italian football is very competitive and there are extremely strong teams here, especially in defence. It will be a difficult League, but a team like Juve have everything it takes to win the Scudetto.
"Do I have a message for the fans? It's a great pleasure to be part of a club like Juve and I hope to bring them immense joy."
