Xabi Alonso transitioned from a highly successful football player to a respected manager, achieving significant milestones in both careers. After making his first-team debut for Real Sociedad in December 1999, Xabi Alonso was appointed team captain by manager John Toshack in January 2001 at 20, leading the team to avoid relegation. His instrumental leadership and accurate passing contributed to Real Sociedads La Liga runner-up finish during the 200203 season, earning him the Best Spanish Player award from Don Balón in 2003. Alonso made his international debut for Spain that same year, beginning a decorated career with the national team.
In 2004, Alonso moved to Liverpool for a transfer fee of £10.5 million. His inaugural season culminated in winning the UEFA Champions League in 2005, where he notably scored in the final against AC Milan during the ‘Miracle of Istanbul.’ He continued his success at Liverpool, winning the FA Cup and the FA Community Shield in 2006, famously scoring two goals from his own half against Luton Town and Newcastle United that year. His international career flourished with Spain, achieving victory in the UEFA European Championship in 2008 and the FIFA World Cup in 2010. Alonso then joined Real Madrid in 2009 for £30 million, where he secured a La Liga title in 2012, two Copa del Rey titles (2011, 2014), and another UEFA Champions League in 2014.
His coaching ascendancy continued with his appointment as head coach of Bayer Leverkusen in October 2022. Alonso orchestrated a historic 2024 season, guiding the team to an unprecedented unbeaten domestic double, securing their first-ever Bundesliga title and the DFB Pokal, alongside the DFL-Supercup. This exceptional performance led to his appointment as head coach of Real Madrid in June 2025, marking a significant return.
