La Liga title rivals Barcelona and Atletico Madrid face off yet again tonight, but this time it's in their huge Champions League tie.
The two sides are currently locked in a battle for glory in domestic action, as Diego Simeone's Atletico sit top of La Liga, just one point ahead of second placed Barca, and they will take their rivalry into continental action tonight.
They have already met three times this season. They went head to head before the season in the Spanish Super Cup, which Barcelona clinched with an away goals win over two legs, whilst their La Liga clash ended in a 0-0 stalemate.
With two sensational goalscorers in Lionel Messi and Diego Costa, few would predict another bore draw at the Camp Nou tonight, with many hoping to catch a glimpse of two of Spain's finest sides battling each other.
