Few feel the Basque coach will start with the same players that saw off Inter Milan in Wednesday's Champions League win.
No-one feels that Barcelona coach Valverde will field the same side in El Clasico as to that which started midweek in the Champions League win over Inter at Camp Nou.
The games against Tottenham, Valencia, Sevilla and Inter have seen a pattern exist and can offer us an insight to the starting XI the Basque coach may opt to select tomorrow when Real Madrid visit Camp Nou.
Ter Stegen. The German keeper is the undisputed number one between the sticks for Valverde.
Semedo. The Portuguese player is in rich form and may be one of the surprises in Valverde's starting XI.
Piqué. Delivered a sublime defensive display against Inter.
Lenglet. Was troubled by Inter's Icardi at stages during the 2-0 Champions League win.
Alba: Scored on Wednesday' and still an explosive for for Barça on the wing.
Busquets. The Spain international only lost one ball in the tie against Inter.
Rakitic. On target against Tottenham and Sevilla and the provider of an assist in the game against Inter.
Arthur. The in-vogue player at the moment at Camp Nou.
Sergi Roberto. The "surprise" of El Clásico.
Suárez. Always hungry for goals.
Coutinho. A perfect setting for the former Liverpool player to explode.
