First, Ronaldo is second to none in helping the team win!
Cristiano Ronaldo is a key figure. As long as Cristiano Ronaldo is in the team, the strength of this team will make the opponent fearful! It can be seen from Cristiano Ronaldo's experience in these years that Cristiano Ronaldo is really powerful. He can not only give a good defensive formation to suppress opponents, but also help teammates create opportunities! Real Madrid can see the true value of Ronaldo by comparing the two stages of owning Ronaldo and losing Ronaldo! Now Juventus' events are getting better and better, which is the credit of Cristiano Ronaldo, so his role in the team is really crucial!
Second, C Ronaldo has the highest winning percentage in the Champions League:
C Ronaldo's performance in the Champions League is really incomparable with him. Even the powerful Messi has no such achievement as Cristiano Ronaldo. C Ronaldo has won a series of victories in the Champions League, and his strong aggressiveness is not available to other players. We can look at Juventus, where Cristiano Ronaldo just moved. This team achieved excellent results in the Champions League last season, and they are likely to win the championship in attack this season.
As can be seen from the above description, Ronaldo's winning percentage in the Champions League is really high, and at the same time, he is very skilled in controlling the team, which other players can't do at all, so it is absolutely correct to say that Ronaldo is the first European champion.
