Cristiano Ronaldo's arrival from Real Madrid has been hailed by Mattia Caldara as a stimulus for the Serie A champions.
Ronaldo signed a four-year deal with Juve to complete a deal worth €112 million , ending a trophy-laden nine years in La Liga.
The Portugal captain will now have a chance to add to the English and Spanish league titles he has already won, with Juventus hunting an eighth consecutive Scudetto.
And Caldara, who joins Juve for the 2018-19 term after spending last season on loan at Atalanta, is thrilled he will be lining up with Ronaldo.
