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.
Only blaming Ronaldo unilaterally for Al Nasr's poor performance, of course that assumption is very wrong. Because basically a football team has 11 players on the field, so is it right to only blame 1 player? It is certain that this is not right. Because basically all football players can't bring their team to victory by themselves, and vice versa. So people who blame Ronaldo unilaterally for Al Nasr's poor performance, I think those people really don't see how total Ronaldo is at Al Nasr's. It can even be said that Ronaldo is the player who has the most dedication to Al Nasr. Because since Ronaldo joined Al Nasr, he has done many things for Al Nasr. But the problem of Al Nasr having difficulty becoming champions in the Saudi Arabian league, this is not Ronaldo's fault. But it is caused by the imbalance of the squad owned by Al Nasr.
Because if we look at Al Nasr when competing, Al Nasr always has difficulty when facing counterattacks from the opposing team. This proves that Al Nasr's back line is very bad. Because basically in my opinion Al Nasr often uses an attacking strategy and that is natural, because in the front line Al Nasr has very good players. But the problem is Al Nasr's back line is very bad, and that makes the attacking strategy ineffective, because it is difficult when facing the opponent's counterattack. Therefore, in my personal opinion, Al Nasr's coach is better off using another strategy, which can make Al Nasr's defense a little better, but can be sharp when attacking. And I emphasize again, that we cannot only blame Ronaldo for Al Nasr's poor performance.
