Barcelona welcome Atletico Madrid to Camp Nou for arguably the biggest game of the season thus far.
These two have been head and shoulders above the 18 other teams in the division so far, Barca winning 14 of their 15 fixtures, Atleti 12.
Diego Simeone’s side have tended to stumble in the big games though, losing to Valencia and Real Madrid, and if they do so again on Sunday night they will fall nine points behind the Blaugrana.
The Rojiblancos certainly aren’t lacking confidence though.
“Do I fear Lionel Messi? No, I am not afraid of anyone,” insisted goalkeeper Thibaut Courtois.
“It motivates me to face a player like him,” added defender Filipe Luis.
Atleti have conceded 24 goals in their six Camp Nou visits.
Kick off: Sunday December 16, 8.00 (BST)
