Newly elected president Joan Laporta's appointment of Frank Rijkaard as coach and the signing of Ronaldinho in 2003 marked the beginning of another spell of sustained success. In 2005 Barcelona once again won the La Liga championship, and retained it the following season. In May 2006 Barcelona defeated Arsenal in the Champions League final, coming back from 0–1 to win 2–1 in the last fifteen minutes. Three years later, the club beat Manchester United 2–0 in the 2009 Champions League final, having already won La Liga and the Copa del Rey that season, to become the first Spanish side to complete the treble. In December 2009, Barcelona won the FIFA Club World Cup, having also won the Spanish and European Super Cups, thereby completing an "unprecedented sextuple".
