Question: In 2009, what series of wins did the team who won the first match in the 1943 Copa del Generalissimo achieve?

Knowledge 1: FC Barcelona
In 1943, Barcelona faced rivals Real Madrid in the semi-finals of Copa del Generalísimo (now the Copa del Rey). The first match at Les Corts was won by Barcelona 3–0. Real Madrid comfortably won the second leg, beating Barcelona 11–1. According to football writer Sid Lowe, "There have been relatively few mentions of the game [since] and it is not a result that has been particularly celebrated in Madrid. Indeed, the 11–1 occupies a far more prominent place in Barcelona's history." It has been alleged by local journalist Paco Aguilar that Barcelona's players were threatened by police in the changing room, though nothing was ever proven. [SEP] Knowledge 2: FC Barcelona
Barcelona is one of three founding members of the Primera División that have never been relegated from the top division, along with Athletic Bilbao and Real Madrid. In 2009, Barcelona became the first Spanish club to win the continental treble consisting of La Liga, Copa del Rey, and the UEFA Champions League, and also became the first football club to win six out of six competitions in a single year, completing the sextuple in also winning the Spanish Super Cup, UEFA Super Cup and FIFA Club World Cup. In 2011, the club became European champions again and won five trophies. This Barcelona team, which reached a record six consecutive Champions League semi-finals and won 14 trophies in just four years under Pep Guardiola, is considered by some in the sport to be the greatest team of all time. In June 2015, Barcelona became the first European club in history to achieve the continental treble twice.
