Guillem Balague and Graham Hunter look at the tactical battles and possible line-ups ahead of Wednesday's huge clash at the Camp Nou between Barcelona and Atletico Madrid.
Champions Barca head into the eagerly-anticipated contest fresh from their 5-1 thumping of Leganes, while Atletico head to Catalonia in fine form after they ruthlessly dispatched Sporting Gijon 5-0.
Both sides adopted new tactics and formations in their previous La Liga outings, a point which Guillem and Graham delve in to before asking whether there will be a similar occurrence when the two sides meet on Wednesday.
With Atleti boss Diego Simeone confirming his contract at the Vicente Calderon has been reduced from 2020 to 2018, the Argentine's legacy is also discussed ahead of his latest attempt to claim at first victory against Barca while in charge of Los Rojiblancos.
