Former Real Madrid and Spain goalkeeper Iker Casillas retired from football at the age of 39.
Casillas made 725 appearances for Real during a 16-year career at the Bernabeu, winning three Champions League titles and five La Liga crowns.
He also helped Spain win the 2010 World Cup and two successive European Championships in 2008 and 2012.
Casillas joined Porto in 2015 but has not played since suffering a heart attack during training in April 2019.
During his recovery he was given a role in the club’s coaching staff in July 2019.
He made 156 appearances for the Portuguese team, winning two Primeira Liga titles and a Portuguese Cup.
Casillas won 167 international caps for Spain between 2000 and 2016. Only Sergio Ramos has made more appearances for the national team.
Real Madrid defender Ramos posted a photo of himself with Casillas on Twitter as a tribute to his former teammate.
Announcing his retirement on Twitter, Casillas said: “The important thing is the path you take and the people who accompany you, not the destination to which it takes you.
“I think I can say, without hesitation, that this has been the dream path and the destination. ”
Real Madrid have said Casillas, who joined the Spanish giants at the age of nine, is the best goalkeeper in the club’s 118-year history.
“Real Madrid want to show their appreciation, admiration and love for one of the greatest legends of our club and of world football,” read the club’s website.
“Iker Casillas belongs to the heart of Real Madrid and will remain so forever. ”
In February, he announced his intention to run for president of the Spanish Football Federation (RFEF), before stepping down later due to the “exceptional social, economic and health situation” that the country experienced during the Covid-19 pandemic.
