Ronaldo's position at Juventus was only as a complement, when Ronaldo came, Juventus was at the peak of its glory. Ronaldo came to Juventus at the right time, even without Ronaldo Juventus had won the Italian League in a row. Now just look at Manchester United's performance, if Juventus' success is considered the Ronaldo effect, why at Manchester United Ronaldo cannot improve Manchester United's performance.
No, when at Juventus ronaldo became Juventus' goal machine. If I'm not mistaken he made 101 goals during his 134 games with Juventus. So at that time Juve became in need of Ronaldo, when Roaldo Was absent Juve often had difficulty scoring goals. The problem continued when ronaldo left, Dybala could not perform consistently, Morata was the same. They kind of lost confidence making it difficult to score. In fact they were hard to win in the early match after ronaldo left.

https://id.wikipedia.org/wiki/Cristiano_RonaldoCristiano Ronaldo has always been a good player for the team he plays for. Manchester United, Real Madrid, it's clear he helped the team a lot to win all competitions, Juventus. But it can be said that Juventus already has a squad that can dominate the league, but after Ronaldo arrived, it was seen that Juventus depended on Ronaldo's presence in the match.
Ronaldo gait at Juventus so far has been quite good and he helped Juventus win several domestic cups, but unfortunately Juventus, which previously brought Ronaldo to get the Champions League trophy, had to bite their fingers because they continued to fail in Europe, even so after Ronaldo left for Manchester, juventus looks quite shaky, the proof is that we can see at the beginning of the season how bad the performance of juventus was after ronaldo left and they didn't even enter the Scudetto competition this season and this clearly shows that juventus dependence on ronaldo is very big.
