On 22 December 2008, Busquets signed a contract extension until 2013 with a buy-out clause of €80 million. On 7 March 2009 he scored his first league goal, in a 2–0 home win over Athletic Bilbao. On 27 May 2009, having been regularly played as he competed for the spot with internationals Seydou Keita and Yaya Touré, he also featured in Barcelona's starting eleven in the Champions League final, a 2–0 win over Manchester United in Rome; with that victory, Carles Busquets and Sergio Busquets became only the third father-and-son combo to both have won Europe's top club competition playing for the same team, joining Cesare Maldini and Paolo Maldini (won it with A.C. Milan) and Manuel Sanchís and Manolo Sanchís (Real Madrid).
