The problem is only one, or is better to say, the main question is always the same, and taht question is.
Is Cristaino Ronaldo goals compensating his not so much contribution on team work? Or better to say, if any other younger star play in the Cristiano Ronaldo spot, can the Al Nasrr have better results?
For me this is not an easy question, but Al Nasrr needs to think about it aside of his renewal contract.
My answer is maybe no or maybe even yes. He has actually proven it based on what Cristiano Ronaldo has given and he has even broken a record. Ronaldo's personal experience is also a main factor or even a key in his achievements. I personally see that the Al Nassr team is not overly reliant on Cristiano Ronaldo alone. And Ronaldo also does not try to do everything by himself as we have seen several times in the past matches. So I think Al Nassr still needs Ronaldo's performance to strengthen the team. But I personally prefer to see Al Nassr revamp their defense, where they seems disorganized and even makes mistakes in crucial matches. And I think the front line is already quite good. However I think Al Nassr needs some good players for the defense as many people expect. So they can establish good cooperation with each other on every line to be able to create a neat performance in the next matches.
