Real Madrid president Florentino Perez paid a tribute to the club's former goalkeeper Iker Casillas, who officially announced the end of his playing days on Tuesday, more than a year after his last match. The 39-year-old Casillas was with Portuguese club Porto but hadn't played competitively since a heart attack in May last year. Real Madrid called Casillas "one of the biggest legends of our club and of world football" and "the best goalkeeper in the history of Real Madrid and Spanish football." Casillas played 725 matches with Madrid's first team over 16 seasons, winning 19 titles. He joined the club at age 9. He played 167 matches for Spain and won the Under-20 World Cup. Casillas this year contemplated running for the presidency of the Spanish soccer federation but withdrew his candidacy amid the coronavirus pandemic.
