If Al Nasr makes a big enough offer for Ramos, I think he will be willing to play for Al Nasr. The reason is, at almost 40 years old, Ramos certainly won't have many choices in choosing a club. So if a club offers him a contract with a high enough salary, he will definitely accept it. Moreover, if Al Nasr offers him a contract, Ramos will definitely be willing to go to Al Nasr, because he will definitely be able to meet his teammate from Real Madrid (Ronaldo). So if you look at this aspect, it is very likely that Ramos will join Al Nasr before retiring.
And if we talk about Ramos' current performance, it could be said that he still has quite good performance as a defender. The reason is, this season he has often been the main player at Sevilla. Apart from that, even though he plays as a defender, Ramos was also able to score 7 goals for Sevilla in all competitions this season. So, even though Ramos is quite old, he is still very suitable to play at Al Nasr. Because as you said, currently Al Nasr is in need of a defender who has very extensive skills and experience. And of course Ramos fits these criteria very well, because Ramos has a very long experience as a defender, and he also has quite good skills. So it is clear that Ramos is a suitable player to fill the defender position at Al Nasr.
No one doubted Ramos when he played for the team he had a career with, last season Ramos was with Sevilla. Now he is being linked with several clubs, apart from Al Nassr. However, what concerns me is whether there are no defenders who are much younger and stronger for Al Nassr ahead of the coming season. the reason is, for how many seasons if Al Nasrr wants to use Ramos' services. I tried to look at it in terms of popularity, Al Nassr has top players with the players they have now. or, ideally bringing in someone younger than Ramos. By offering him a contract and a high salary, Al Nassr was able to get a more ideal defender who also had the same skills and quality. besides, I'm not sure if Ramos is interested in joining and playing in the Saudi Pro League. as mentioned in the above report, he prefers other leagues. But, we'll see, who knows, Segio Ramos will be interested if he gets an offer from Al Nassr.
Well, IMO, Al Nassr can bring in players who have quality. they already have top players besides CR7, they will also get a tough defender besides Ramos. I'm not saying Ramos is over, but rather about the future progress of the Al Nassr squad itself. or, they can recruit local talent. It's been two seasons, Al Nassr without a League title after bringing in star players. Maybe, now is the time for them to focus on young talent. at least, for the squad's defense line. Or as I said above, that doesn't mean Ramos can no longer be relied on. However, Al Nassr will be much more competitive if they see the local potential or young talents they can bring in.
