I cannot agree with your statement. You are saying that since Ronaldo is not giving 100%, the team's performance is not good, so he is not giving 100% of his effort in this game.
Your idea is completely wrong because I think that a valuable player, a player with a worldwide reputation, never lacks in his effort. In fact, he is giving his all, but old age is hindering him. Since he is old, it is impossible to get anything better than him now.
He is still giving his 100% and individually he is one of the top-performing players for the last three years in the Saudi Professional League. Age maybe having some impact, but then why he is performing much better than younger players such as Jhon Durán and Sadio Mané? Mané has so far scored 20 goals from his 56 appearances for Al Nassr, while Cristiano Ronaldo has 71 goals to his name from just 68 matches. Aleksandar Mitrović, widely regarded as the best forward in SPL right now has 42 goals from 41 matches for Al Hilal (goals per match is still lower than that of Ronaldo).
Your survey really makes me want to say, "Old is gold". Ronaldo has maintained his individuality in the Saudi Professional League by scoring the most goals so far. Even then, if someone says to Ronaldo, "He is not giving his 100% performance, then it is a big shame for him". However, I would say that Cristiano Ronaldo is evergreen, eternal, and a legend. It is doubtful whether a player like him will be born again in the history of the world.
