I agree that they do not depend on Ronaldo alone, but when you pay one player more than you pay all other players combined, you do expect that person to carry your team.
Yes that's correct. in a soccer game, it takes eleven players. Each player has their own role according to their position and expertise. So, football doesn't only depend on one person and in this case, Ronaldo. but as you said, Ronaldo was brought in by All Nassr to boost the team's overall performance. especially when it comes to scoring goals and that's why he's on a high salary. so naturally, so all eyes were on Ronaldo who had shone on the European league scene.
However, Ronaldo is no longer a player that can win games all by himself, and he gets frustrated when his teammates do not score on his passes, this was true back in United too, he passes and expects others to score like how he used to, but nobody can, not even himself. Which is why it's quite expected of him and the team to not get as much as he was paid out of this situation. It's good marketing though, which is all they wanted and they got it, it's amazing marketing and that's all that matters.
Yes, again i agree. Ronaldo can no longer be expected to play like at his young age. Unfortunately, he still has problems with his own ego. in fact, he once said in an interview with Piers Morgan, that he was still capable of scoring tons of goals. now, he plays below the level of European leagues. it should be easy for him, unfortunately he wasn't able to bring out his abilities like he was young. like it or not, Ronaldo has to start adapting at least he can make a big contribution even though he doesn't score in every game. that was all he could do at the moment.
But sorry, marketing what do you mean in this case. fact, his salary sky-high. is it possible, All Nassr will get a much higher profit just for bringing in Ronaldo.
