The name of Ramos shines in the glorious chapter of Spanish soccer. Since March 26, 2005, at the age of 18, Ramos joined the national team and began his glorious journey. His debut was against the Chinese national team, where he wore the No. 15 kit and witnessed Spain's 3-0 victory. Three days later, in the World Qualifier, he chose the No. 19 jersey to celebrate his 19th birthday.
Ramos wore Real Madrid's No. 4 jersey with the national team, but at Euro 2008, he chose the No. 15 jersey in honor of his deep friendship with Puerta. Ramos was devastated by the death of Puerta, who did not close his eyes for 48 hours until his friend passed away. In honor of Puerta, he chose to wear the No. 15 jersey again, and after winning Euro 2008, he wore a white T-shirt with Puerta's head on it to show how much he cherished his friendship.
In 2008, when Spain dominated Europe and won their first World Cup in 2010, Ramos was the starting right back for the national team. As he grew older, he transformed into a center back, partnering with Gerard Piqué, becoming a "love and hate" combination in the club and national team. Ramos said of Piqué: "At the club, we dislike each other; in the national team, we embrace." Piqué also said: "In Madrid, I am treated with great respect, and the relationship with Ramos and others is cordial and special."
From 2008 to 2012, Ramos won two European Cups and a World Cup with Spain, creating a record-breaking season. defending the Euro 2012 title, Ramos and Gerard Piqué reached the pinnacle of their national team careers. In the semi-final penalty shootout, Ramos sealed the win for Spain with a scooped penalty, calling it the most important moment of his life.
On October 13, 2019, Ramos surpassed Casillas as the player with the most appearances for the Spanish national team. A year later, he again set the record for the most appearances for the European national team. However, Ramos missed most of the 2020-2021 season due to injuries and a new crown, and Spanish national team boss Luis Enrique did not select him for the Euro 24 squad. But Ramos' No. 15 jersey went unchosen, perhaps as a tribute to the old captain.
In life, Ramos is a devoted husband and father. He was once a "King of the Sea", but his love life took a turn for the worse when he met Pilar Rubio, eight years his senior, in 2012. The two married at the end of 2012 and have three children. Britain's The Sun newspaper said Ramos had completed a "hat trick" of sons.
