Ronaldo, a former teammate with Isco during his time at Real Madrid, believes the midfielder can play a key role in Max Allegri’s side next season.
Ronaldo and Isco were instrumental players for the Los Blancos between 2016 and 2018.
Isco was among the five players Real Madrid manager, Zinedine Zidane, has identified that will be leaving the club this summer.
Isco’s current deal at Real Madrid will expire in 2022.
The player’s passing and dribbling, as well as positioning make him an ideal option for Juventus as they aim to win their first Champions League since 1996.
