That's a little bit weird but Real Madrid is thinking about hiring Sergio Ramos and returning this player to Real Madrid while Sergio Ramos is getting old and he is out of good form.
Sergio Ramos back to Real Madrid? I haven't read such a news but guess what? I already have a clear picture of Sergio Ramos and Rudiger bullying defenders if this happens.
I don't know what will happen though, but, fingers crossed, I haven't even seen Fabrizio Romano tweeting such even in the last three to four days.
This is a joke, it's impossible for Real Madrid to re-hire the 38 year old Ebrusian player. Currently, Real Madrid's focus is on regenerating its players to become stronger. especially this season maybe the focus will be on their defense. and Centre-Back? I know that Real Madrid need a Centre-Back at the moment, but as you said, it's definitely not Ramos. Ramos was indeed a player who played a very important role in the past, but his era is over and we appreciate that.
I even tried to look for these rumors in the news, but they were old rumors and there were no new rumors. Currently, Ramos' position is 'without club", at his old age, there won't be many top European clubs who want him, unless it's Saudi Arabia, probably.
