Under new manager Pep Guardiola, Barcelona had a historic season, achieving a treble: La Liga, Copa del Rey, and UEFA Champions League. The squad featured stars Lionel Messi, Xavi, Andrés Iniesta, Samuel Eto’o, and Dani Alves, blending youth, experience, and tactical intelligence. Barça played mesmerizing tiki-taka football, dominating possession, pressing high, and creating scoring opportunities with fluid movement. They won La Liga convincingly, defeated Athletic Bilbao in the Copa del Rey final, and triumphed in the Champions League 2–0 over Manchester United at Wembley. This season marked the beginning of Guardiola’s era as one of football’s greatest managerial successes.
