Lionel Messi's rate of scoring for Barcelona and sheer amount of goals over the last decade is nothing short of world-class, but he had to begin that run somewhere.
On May 1, 2005, soon-to-be relegated Albacete were the visitors to Camp Nou and had lost 10 of their previous 11 fixtures, drawing the other, per Gol.com (Spanish).
The Catalans had been at the top of La Liga since Gameweek 6 of the season, a 1-0 victory over Numancia courtesy of a 70th-minute winner from Henrik Larsson.
It's fair to suggest therefore, that a big score and a classic Barca attacking performance was expected.
