Everything you need to know ahead of the Catalans' La Liga clash at Camp Nou on Sunday...
Barcelona need to beat Eibar and hope Real Madrid lose at Malaga as the Primera Division goes down to the wire on Sunday.
Luis Enrique's side are three points behind at the top of the table after Los Blancos won their game in hand at Celta Vigo on Wednesday, but the Catalans will win the title if the two teams finish level on points due to their superior head-to-head record in the two Clasico clashes in 2016-17.
Barca are at home to Eibar on Sunday evening, with Madrid in action at Malaga at the same time.
