Juventus defender Giorgio Chiellini is convinced they are genuine Scudetto challengers this season.
"These new signings have really reinforced the squad. I know it's not easy to compete with Inter and at the end of the day last season they deserved the victory because they were more consistent," he told Sky Sport Italia.
"We have certainly closed the gap with our new buys, but now we need to achieve their level of consistency and not drop stupid points in ridiculous games like we did last year."
He added: "I am curious to see Diego in action, as on television it's a very different matter.
"I know Felipe Melo already, having faced him in Serie A when he played for Fiorentina."
