The most important thing he got is the motivation he has because any player will lose motivation for having good performance time after time when they get older but Ronaldo is a different player with more power and as you said he even doesn't not suffer a bad injury and maybe that's all because of the playing style and file and the training he has in the team, otherwise he could get retired years ago like many other players.
I think it is related to someone's personality. Ronaldo still has a motivation to play with his best because he is a typical person who always wins every competition he joined. He has a winning mentality, he doesn't want to play like an average player. He wants to be the top scorer, he wants to win a trophy, and he wants to create a new record. It is what Ronaldo always thinks in his mind. So, he never lose motivation in his life.
Yep. Ronaldo very rarely get injury because he has a good lifestyle. He also did regular training and never forget to keep his good fitness. Most old players may not really care about his matters, they think they won't play a longer time. But Ronaldo will always think to play as long as possible. That's why he keeps the motivation to keep his physical as well.
It's true that Cristiano Ronaldo is a very ambitious player and he always wants to be the best. But what I like about this player is that he doesn't become selfish just because he wants to be the best. That's why he was always liked by his teammates at the club he joined. Like at Al-Nassr all the players like him and they are even sometimes seen learning from Cristiano Ronaldo in training sessions. For example, now Talisca has excellent kicking sharpness after Cristiano Ronaldo arrived. Talisca was good from the start but he got even better after Cristiano Ronaldo arrived.
But it is truly extraordinary to see that Cristiano Ronaldo rarely suffers injuries. Even though he was often violated hard by opposing players. But yes, he was able to take care of himself so he could avoid injury. He has more hours of training than other players. Even in eating and sleeping patterns, he has an expert who always gives him the best direction. That's why he is someone who can really maintain his stamina at a young age. Because all of this was created from the hard work and high level of discipline that he implemented in his lifestyle.
