Defenders
While Barcelona have started with 3 at the back recently, they should definitely start with the tried and tested back 4. Unarguably the two best centre-backs in the Barcelona squad, Samuel Umtiti and Gerard Pique walk into the starting XI. Blessed with good height and strength, Pique and Umtiti will have to be most alert during set-pieces. Real Madrid are very dangerous from corners and the centre-backs definitely have a match on their hands.
The full-backs will have an extremely crucial role to play. Ever since the departure of Dani Alves, Barcelona have struggled to make an impact on the flanks and Enrique will be hoping that both Alba and especially Sergi Roberto contribute more in the attacking sense.
The back 4 for Barcelona should ideally be: Centre backs: Pique and Umtiti, Left-back: Jordi Alba, Right-back: Sergi Roberto
