Players on the central axis are the top priority of a team's performance, and a poor centre-back will drive your goalkeeper crazy. And the poor full-backs? Take stock of the "top 10" worst defenders in Real Madrid's history.

1. Danilo
Danilo joined Real Madrid for a transfer fee of 31.5 million euros, but his performance did not match his value. During his two seasons at Real Madrid, he made only 56 appearances.
2. Jonathan Woodgate
England centre-back joined Real Madrid from Newcastle in 2004 for a transfer fee of €22 million. Due to a muscle injury that prevented him from playing all season, a year later, he was completely expelled from Real Madrid by a goal against Atletico Madrid, and he quickly returned to England.
3. Walter Samuel
A million more than the previous one, the Argentine centre-back joined Real Madrid for twenty-three million euros due to his outstanding performance at Roma. But he did not fare as expected on the central axis, returning to Italy at the end of the season despite scoring two goals in 30 games. Then in the nine seasons at Inter, he was completely transformed into a domestic idol.
4. Royston Drenter
Dutch midfielder and full-back Drentt played well at Euro 21 and quickly piqued real Madrid's interest. But he couldn't finish with the rest of the Whites, and although he scored a long-range shot from 30 metres away against Sevilla in the Spanish Super Cup, his form has since begun to decline. The way he played, his personality and his fascination with Madrid's nightlife eventually led him away from Real Madrid.
5. Julio Cesar
Nicknamed "Tiger", he finished 21 games at Real Madrid but was under pressure to compete with other centre-backs, leaving him unable to stay in shape and eventually left. In 2000, he won the Champions League with the team, and then traveled to Milan, Benfica, Real Sociedad and Olympiacos.
6. Claude Mir Verdo
Brazilian full-backs in the 90s, a bit of a Cavo rhythm, but left Madrid and returned to Brazil after just three games. In Brazil, he played for São Paulo and Cruzeiro and won the Copa Libertadores.
7. Carlos Sécre tario
Another right-back in the '90s, but this time it was the Portuguese. It was bought from Porto by Real Madrid in 1995. He struggled to replace Sanchez Flores on the flank and, disappointed, returned to Porto and received many accolades.
8. Carlos Diogo
Another right-back, came to Real Madrid with the intention of occupying the main full-back position, but was unsuccessful. He joined Real Madrid from River Plate in 2005 and after 19 games, he was abandoned by then Real Madrid manager Capello. He then moved to Zaragoza and played for six seasons.
9. Spasic
Serbian centre-backs were not in Real Madrid's signing programme, but then-club president Mendoza, after seeing his performance at the World Cup in Italy, decided to make his next bet to invest two hundred million pesetas (Spain's old currency) in him. And after 25 games in a season, he left Osaka.
10. Julian Faubel
The Frenchman, who can play both full-back and winger. But at Real Madrid, we don't see his good performance. After being loaned to Real Madrid by West Ham, he did not play more than 60 minutes in the entire season. His most eye-catching shot was actually a nap on the bench at the Bernabeu.
Although many people are as cute as Marcelo, you have no one to play well.
