He was also outstanding at the Santiago Bernabéu, in Barcelona's unforgettable 3-0 win, and also at Stamford Bridge, in the Champions League match against Chelsea. Injury kept him sidelined for much of the latter stage of the season, but Messi still played a total of 17 league games, 6 in the Champions League and 2 in the Copa del Rey, and scored eight goals.
