On 27 October 2009 the club was eliminated from the Copa del Rey during the Round of 16 by the modest Segunda División B club Alcorcón with a 4–1 aggregate loss. The Spanish daily "Marca" named this match "Alcorconazo" and went on to make many teasing references to Pellegrini. On 10 March 2010, Madrid were eliminated from the Champions League by Lyon in the round-of-16 with a 2–1 aggregate loss. Florentino Pérez issued an ultimatum to Pellegrini after this defeat, warning him that he would be dismissed if he did not win the La Liga title.
