Busquets was again ever-present in 2010–11, even playing as a centre back on occasions. On 27 January 2011, he signed a contract extension that would keep him at the club until 2015 – the buyout clause was increased to €150 million. On 8 March 2011, playing at centre back, he scored an own goal from a corner kick against Arsenal, in the season's Champions League round-of-16, levelling the score at 1–1; Barcelona eventually won the game 3–1 (and 4–3 on aggregate). On 28 May, Busquets played the full match during his side's 3–1 Champions league final victory against Manchester United at the Wembley Stadium.
