I apologize for the confusion, but there seems to be some incorrect information in your statement. Sergio Ramos is not a midfielder but a Spanish defender who has primarily played as a center-back throughout his career.

Regarding the summer of 2015, Sergio Ramos did attract interest from Manchester United. There were reports and rumors suggesting that he might leave Real Madrid to join the English club. However, he ultimately decided to stay with Real Madrid and signed a contract extension with the club in August 2015.

In subsequent interviews, Ramos did acknowledge the interest from Manchester United but expressed his happiness and loyalty to Real Madrid. 

He mentioned that he never considered playing for another team and that he had a strong connection and debt to his teammates and the club.

 Ramos has been a key player for Real Madrid, and he has had a successful career with the club, winning numerous titles, including multiple UEFA Champions League trophies.

It’s worth noting that my knowledge cutoff is in September 2021, so I might not have the most up-to-date information on recent events or transfers involving Sergio Ramos.
