On June 21, 2010, Olympique de Marseille reported that a deal had been struck with Osasuna for Azpilicueta's move in a four-year contract for EUR 7.6 million. The Navarrese announced the agreement a week later, with the transfer price potentially rising to EUR9.5 million based on appearances. The club also confirmed that another Spaniard, defender Jordi Mboula, would be joining them on a free transfer. Before moving to Spain, Azpilicueta played for Chelsea and St. Mirren in the English Premier League. He made his debut for Chelsea against Portsmouth on May 23, 2005, and scored his first goal three games later against West Bromwich Albion. After making 39 appearances for Chelsea, he moved to Scotland where he spent two seasons with St. Mirren. He helped the club win the Scottish Cup in 2006 before leaving to join Marseille. In France, Azpilicueta has become a regular at Marseille's left back position and has earned 35 caps for his country over the last eight years. He was part of the Spain squad that won the European Championships in 2012 and 2016, as well as the Olympics four years ago in London. He joined Marseille from Chelsea for an initial fee of €7.5 million (U$10.5 million) with additional bonuses depending on appearances.
