Guardiola's first competitive game as coach was in the third qualifying round of the Champions League, in which Barça comfortably beat Polish club Wisła Kraków 4–0 in the first leg at home. They then lost 1–0 in the second leg, but progressed with a 4–1 aggregate victory. Promoted Numancia also defeated Barcelona in the opening match-day of the La Liga, but the team then went on an undefeated streak for over 20 matches to move to the top of the league. Barça maintained their spot atop La Liga's table, securing their first league title since 2006 when rivals Real Madrid lost at Villarreal on 16 May 2009. The most important match, however, was on 2 May when they defeated Real Madrid 6–2 at the Santiago Bernabéu Stadium. The league title was the second piece of silverware in Guardiola's first season at the Camp Nou. Earlier on 13 May 2009, Barcelona won the Copa del Rey, defeating Athletic Bilbao by 4–1.
