After the season, Senderos committed his long-term future by signing an improved five-year deal. In the 2005 FA Community Shield, he was beaten by Didier Drogba for both goals as Arsenal lost 2–1 to Chelsea. During the 2005–06 season, he scored his first Arsenal goal in a 2–1 loss to West Bromwich Albion on 15 October, and again in a 7–0 win over Middlesbrough on 14 January. He played in Arsenal's run to the final of the UEFA Champions League in 2005–06, but was an unused substitute in the final, which Arsenal lost to Barcelona.
