Iker Casillas Fernández Spanish goalkeeper who plays for the Spanish La Liga club Real Madrid

Iker Casillas Fernández born 20 May 1981 is a World Cup-winning Spanish goalkeeper who plays for the Spanish La Liga club Real Madrid and serves as captain for both the Spanish national team and Real Madrid. As captain of the national side, he led a young Spanish team to their first European Championship in 44 years, his first senior international honour. In 2010, he led Spain to their first ever FIFA World Cup and won the Golden Glove for the tournament's best goalkeeper.

Since bursting onto the scene as a teenager, Casillas has been recognised as one of the best goalkeepers in Europe, illustrated by the many awards he has received. He was nominated for the European Footballer of the Year award twice, ranking fourth overall in 2008 and continuing to be the highest-ranked goalkeeper again in 2009. At the end of 2009 he was voted into the UEFA Team of the Year for the third consecutive time. As of July 2010 Casillas is one of a very select group of players who have won all major club and national championship titles. In 2010, he was awarded with the Sports Prince of Asturias Award. On 19 October 2010, Casillas became the most capped goalkeeper of all time in the UEFA Champions League.

Casillas is a product of Real Madrid's youth system, and started in the junior squad during the 1990–91 season. He was first called up to the first team on the 27 November 1997 at age 16 to face Rosenborg in UEFA Champions League 1997–98, but it wasn't until the 1998–99 season that he debuted in the senior side, substituting Bodo Illgner. By the next season, he relegated Illgner to the bench and became first choice. In 2000, he became the youngest ever goalkeeper to play in a Champions League final when Real Madrid defeated Valencia 3–0, just four days after his nineteenth birthday.

Casillas lost his place in the side to backup César Sánchez after a patch of bad form during the 2001–02 campaign, but redeemed himself when Sánchez suffered an injury in the last minutes of 2002 Champions League final match. Casillas came on and pulled off several brilliant saves to deny a rampant Bayer Leverkusen the Champions League crown. The Whites won 2–1 and Casillas has maintained the number 1 shirt ever since.

The 2007–08 season was a fruitful season for Casillas. He helped Real Madrid reclaim their 31st La Liga title and conceded only 32 goals in 36 games to claim the Zamora Trophy. On 14 February 2008, he and then club captain Raúl were awarded new contract extensions. Casillas signed a contract extension that will keep him at the club until 2017, with an automatic extension if he plays 30 competitive matches during the final season of the contract and a buy-out clause of £113 million. His performances earned him a spot in the UEFA Team of the Year for the second time.

In February 2009, Casillas equalled Paco Buyo's record of 454 matches played (for a goalkeeper) and has since surpassed it to become Real Madrid's most-capped goalkeeper of all time at only twenty-seven years old. During the 2009 summer transfer window, some Spanish media reported that Manchester City had launched a record £129 million bid for the goalkeeper. However the club denied the allegations saying that no such offer had been made. Manchester United had been rumoured to have enquired about him, but no price was announced. He had been linked with other Premier League clubs before but Casillas himself stated that he "had no intention of leaving" his boyhood club.

During the 2009–10 season on 4 October in a game against Sevilla F.C., Casillas made an extraordinary save; he ran from one side of his goal to the other and denied Diego Perotti in a one-on-one close range encounter. After the match, he received praise from fellow Spanish goalkeepers and England goalkeeping legend Gordon Banks, who stated "Casillas' reflexes are incredible. If he continues to play this well he will become one of the best goalkeepers in the history of the game." Europa Press reported that Casillas was the 2nd most popular Spanish sportsman on the internet throughout 2010. The study performed by company Vipnet360 examined the web presence on platforms like Facebook, Twitter and YouTube.

Casillas is currently the second-most capped goalkeeper in the history of the Spanish national team, behind Andoni Zubizarreta, who appeared in 126 matches.[16] Following his full international debut at the senior level against Sweden (at 19 years and 14 days), Casillas was an unused substitute at Euro 2000. He was part of the roster for the 2002 World Cup, initially as the understudy to Santiago Cañizares. Coincidentally, Casillas became the first-choice goalkeeper when Cañizares had to withdraw from the tournament due to injury from a freak accident. At 21, he was one of the youngest first-choice goalkeepers in the tournament. He played an instrumental role in Spanish progression when he saved two penalties in the shoot-out during the round of 16 match against the Republic of Ireland, earning him the nickname "The Saint".

Casillas played in all eight Group six fixtures during Euro 2004 qualifying, conceding just four goals. He kept a clean sheet in the second leg victory of the playoff against Norway which ended 3–0 in Oslo, and started all of Spain's Euro 2004 matches. He was the first choice for the 2006 FIFA World Cup, captaining the team twice, but could not prevent La Roja from losing 3–1 to a Zidane-inspired France in the Round of 16.

With the exclusion of his ex-Real Madrid teammate Raúl from the squad for Euro 2008, Casillas was given the captain's armband. He started the first two Group D games against Russia and Sweden before being rested in place of second-choice goalkeeper Pepe Reina for Spain's group stage elimination of Greece. Casillas saved two penalties from Antonio Di Natale and Daniele De Rossi as Spain eliminated Italy in the quarterfinals with a 4–2 shootout win following a goalless draw on 22 June. Spain later went on to win the competition with a 1–0 win over Germany in the final on 29 June; Casillas kept clean sheets for the quarterfinal, semifinal, and final matches, with Sweden's first round goal by Zlatan Ibrahimović being the last one scored against him. On 29 June 2008 Casillas became the first goalkeeper-captain to lift the UEFA European Championship trophy when Spain beat Germany 1–0 in the final.

In October 2008, Casillas and deputy in goal Pepe Reina broke the national record for the longest time spent without conceding a goal. The pair went unbeaten for 710 minutes, longer than Spain's longest-serving gloveman Andoni Zubizarreta and Paco Buyo. Wesley Sonck of Belgium ended their goalless streak when he scored against them a 2010 World Cup qualifying match.

One of his saves during the quarterfinals versus South Korea during the 2002 FIFA World Cup was rated by FIFA as one of the top 10 saves of all time. Casillas was the highest ranked goalkeeper (4th place) in the 2008 Ballon d'Or behind Cristiano Ronaldo, Lionel Messi and national teammate Fernando Torres.
