Ramos is a strong defender, but we must know that he is no longer in their best form. I am not pessimistic about his contribution, he may bring positive impact for Sevilla defense line. However, with the current situation on Ramos, I don't think Ramos can significantly improve the strength of Sevilla defense. Moreover, Ramos often gets injured, he may be absent in some matches.
Sevilla actually has a good striker, En-Nesyri. This player often shows amazing contribution for Sevilla. But it is good if Sevilla has another strong striker, it will strength the power of Sevilla attacking. Anyway, there is something crucial for Sevilla, they lost their main goalkeeper. I think they also need a strong goalkeeper now.
Currently, the best contribution Ramos can make is his experience as the world's best defender for several years. I think this will really help Sevilla's defense. At least they will have a strong and neat defense line.
And for strikers, I think Youssef En-Nesyri is quite good. Although they still need additional attackers to strengthen the attack line.
Losing a world-class goalkeeper is certainly a very worrying thing. I think the substitute goalkeeper is at a much different level to the main goalkeeper. Hopefully Sevilla can fix this as soon as possible.
I wouldn't put Ramos in the list of the best defenders in the world right now. Because he is now more than 37 years old. And at the age of almost 38 it is very difficult to perform regularly with the team while maintaining fitness . Sevilla are unlikely to have Ramos in the squad for every match on a consistent basis. He will now face very few injuries. And that's what we saw during his time at psg .
But ramos is a very experienced defender. Experienced defenders like ramos are few and far between these days. Sevilla could use the experience of coach Ramos to try and strengthen their defence. And Sevilla will certainly benefit from it. Sevilla's defense was very weak. Hopefully, having Ramos in the squad will give Sevilla players some confidence as well.
