Guardiola made his senior debut on 14 October 1992 in 0–0 draw with Northern Ireland at Windsor Park in a World Cup qualifier . In the same year, Guardiola captained Spain when they won a gold medal at the Barcelona Olympic Games . It was in this year when he won the Bravo Award , voted the world's best player under the age of 21. Between 1992 and 2001, Guardiola played over 47 times and scored five goals for the senior Spain team . He was a member of the Spanish team during the 1994 World Cup , where they reached the quarter-finals, losing 2–1 to Italy . He fell out of favour with Javier Clemente , the Spain manager, due to differences and disagreement between the two, and missed out on Euro 1996 . He suffered a career-threatening injury in 1998, which kept him out of the 1998 World Cup , but he later played at Euro 2000 , where he led Spain to yet another quarter-final appearance, this time losing to France by the same margin, 2–1. He led the Spain midfield until his final appearance for la Roja , in 1–0 win in a friendly against Mexico on 14 November 2001, and scoring his last international goal against Sweden in a 1–1 draw, in his 45th appearance.  
On 26 June 2017, De Boer was announced as the new manager of Premier League side Crystal Palace , replacing the recently retired Sam Allardyce . He signed a three-year deal with the South London club,   but was sacked 10 weeks later when Palace lost their first four league matches of the season without scoring a single goal – the first team in 93 years to have begun a top-flight season in such a fashion.  He left having managed the team for only 450 minutes of Premier League game time, making it the shortest reign of the Premier League era (in terms of number of matches, rather than number of days).  De Boer's only win came in an EFL Cup second-round game, in which Crystal Palace won 2–1 against Ipswich Town .   He was replaced by Roy Hodgson .
