Clubs: Athletic Club, FC Bayern München
• Born in Estella, close to Pamplona, he started out with local club CA Osasuna but was scouted at an early age by Athletic before he had a chance to play for their first team. An immediate success at the Estadio San Mamés, he made 35 Liga appearances in his debut campaign, aged just 18, and scored a memorable double in a 2-0 win at RC Deportivo La Coruña.
• Continued to blossom over the next few campaigns as Athletic's central midfield conduit and helped the club into the 2009 Copa del Rey final − a 4-1 defeat by FC Barcelona − after which he made his European debut in the 2009/10 UEFA Europa League.
• Played for Spain at the 2009 UEFA European U21 Championship in Sweden and made his senior debut a year later, in an Innsbruck friendly against Saudi Arabia, before earning a surprise call-up for the 2010 FIFA World Cup, where he made one brief substitute appearance.
• Promoted to U21 skipper for the 2011 finals in Denmark, he led Spain to victory, starting all five matches; made two appearances in UEFA EURO 2012 qualifying − away to Lithuania and the Czech Republic − and by the end of 2011 he had yet to play a senior international on home soil.
• Appeared in two cup finals in May 2012, both of which ended in a 3-0 defeat for Athletic – the UEFA Europa League (v Club Atlético de Madrid) and Copa del Rey (v Barcelona); made one substitute appearance as Spain retained the European Championship.
• Became the most expensive player in German history when he joined Bayern in August 2012 for €40m. A Bundesliga title winner in his first season, he featured in all but one of the club's games in their triumphant 2012/13 UEFA Champions League campaign.
