I didn't find this rumor anywhere and its not going to happen for Madrid in this case. We are aware that Ramos is a legend for Madrid, but to let him return to Madrid with his current condition which is already entering the final age for a professional athlete because it is already 38 years old then of course it will be very difficult for Sergio Ramos to be in the Madrid squad with a busy schedule and greater competitiveness than other clubs.
Even though there may be a rumor that ive never seen at this time but this will never be a reality because im quite sure this is just a news story that is intended to make player transfers busy, not to be a reality because indeed for player transfers, especially players who are quite popular in the end, its always an interesting topic that can be used as a headline in media .
I have also checked the internet to see if any online sports news reported the news of Sergio Ramos going back to Real Madrid and I don't find any. He might be a good player who has contributed immensely to the success of Real Madrid but his time has passed. He is not getting younger and I doubt if he can be able to play at the top level like he did before. He might return to Real Madrid as a coach in the future and not as a player.
The player was happy playing in his boyhood club Sevilla.
He had to turn down offers from Saudi Arabia and Turkey in favor of Sevilla to fulfill his dream of returning to the club. Sevilla was willing to extend his contract but he decided to leave because of the poor management of the club. For now, there is speculation that he might consider moving to MLS and Saudi Arabia, but he has not made any statement yet.
But indeed with his current age it would actually be better if he did retire because after all he was 38 years old and it would be very difficult for Ramos if he was looking for a new club, especially for big competitions. Indeed he can still be in smaller clubs or competitions such as MLS or SPL but with that I think the impression becomes not beautiful later because seeing Ramos' goal at Sevilla is to repeat and close his career because he was born in Sevilla before being brought to Madrid and it would be very good if he ended also in Sevilla.
But all decisions return to Ramos later because he certainly knows what his qualifications are at his current age, it's just that for Madrid I think this is still too big because with Ancelotti's plans now I still feel that Madrid will look more at players who have potential for the long term rather than the short term especially if Ramos comes at most his contract is only one season.
