Ten years ago, Liverpool came from behind to beat Barcelona 2-1 in the Camp Nou in the first leg of the Champions League round of 16.
An ugly spat between Craig Bellamy and John Arne Riise before the match threatened to disrupt the Reds' preparations, yet the same players scored the goals for a memorable victory that set the club on their way to a second Champions League final in three seasons.
Lionel Messi wasn't quite the phenomenon he would become, but Barcelona were still the reigning European champions. Knocking them out was a major achievement.
