Barca’s 2-2 draw at Celta Vigo allowed Real Madrid to open up a two-point lead at the top of the table by beating Espanyol 1-0 on Sunday night.
Real’s superior head-to-head record means they will be champions if they finish level on points with Barca, so Quique Setien’s side now needs to make up three points on their Clasico rivals during the run-in.
With Barca out of sorts and needing a victory, an in-form Atletico side is perhaps the last team they would want to face – but Lionel Messi & co. know there is no room left for error.
Setien released a list of 23 players to tackle Diego Simeone’s at the Camp Nou Stadium in a post via the club’s official website on Monday.
The Catalan club is in the second position on the La Liga table with 11 points ahead of third-place Atletico.
Ter Stegen, N. Semedo, Piqué, I. Rakitic, Sergio, Arthur, Suárez, Messi, Neto, Lenglet, Griezmann, Jordi Alba, Braithwaite, S. Roberto, Vidal, Umtiti, Junior, Iñaki Peña, Riqui Puig, Collado, Ansu Fati, R. Araujo and Monchu.
