Xabier Alonso Olano (Tolosa, Guipúzcoa, Spain, November 25, 1981) is a former Spanish soccer player and coach. Since June 1, 2019, he has directed the Real Sociedad de Fútbol "B", a subsidiary of the San Sebastian team. 
Formed in the lower categories of Antiguoko and Real Sociedad, he made his debut in the First Division with the San Sebastian team in the middle of the 2000-01 season, after being re-caught from his transfer to the Eibar Sports Society. He stayed in San Sebastián for four seasons, reaching the league runner-up in 2002-03, where he was designated as the "best Spanish player" of the championship by Don Balon magazine. In 2004 he was transferred to Rafa Benítez's Liverpool Football Club.  In the first of his five seasons with the Anfield club, he was proclaimed European champion, after the epic final in Istanbul in 2005. In 2009 he returned to Spain to sign for Real Madrid Club de Fútbol (club that in 2004 was about to sign him).   With the club from the capital he won a League, two Cups (2011 and 2014), a Super Cup and his second Champions League, «La Décima» for the club. After five seasons in Madrid, he signed for Bayern Munich under Pep Guardiola in 2014.  He spent three years at the Bavarian club, until his retirement at the end of the 2016-17 season, and after 18 years as a professional. [ 7]
He was an absolute international with the Spanish national team for 11 years (2003–2014), totaling 114 caps and 16 goals.  With her he was proclaimed double champion of Europe, in 2008 and 2012, and world champion in 2010.
He was born on November 25, 1981 in Tolosa, Guipúzcoa. He is the son of the former footballer Periko Alonso, and his two brothers are also involved in soccer, one as a footballer and the other as a referee.  Xabi Alonso lived in Barcelona for the first six years of his life and moved to Saint Sebastian. It was there that his passion for soccer began while playing in Playa de la Concha.  On the sands of this beach, Alonso starred in several battles of exhibitions of soccer technique with Mikel Arteta, both neighbors.  Xabi's football was influenced by that of his father, Periko, but the young Alonso took more pleasure in passing the ball optimally than shooting at goal.  At an early age, Xabi decided to play as a defensive midfielder: a role that would help him learn how to distribute the ball well. 
At the age of 16, Alonso traveled to the Irish town of Kells to learn English.  While there, Xabi enjoyed playing Gaelic football with other local boys.  Even today, he is a fan of the sport and the Meath GAA, one of the Irish teams in the sport. 
Alonso and Arteta were ambitious and dreamed of playing together for Real Sociedad when they were older. Although they attended different schools, the two young footballers joined Antiguoko, the local club they played with on weekends. His performances at this modest club attracted the attention of scouts from San Sebastian to play for Real —in the case of Alonso— and Catalans, to play for FC Barcelona —in the case of Arteta.  However, Xabi did not he only went to the Real, since his brother Mikel also signed for the royalists. 
Alonso progressed in the Real Sociedad youth teams and managed to reach the first team at the age of 18.  He made his debut on December 1, 1999 against CD Logroñés in a Copa del Rey match.  Later , the young midfielder did not play any other game, but in the following campaign the Toulouse player enjoyed more minutes. In the 2000-01 season, Javier Clemente decided to transfer Alonso to SD Eibar of the Second Division to continue his progression. However, in January 2001, the Real was located in last position
