Garrido's full 18-man squad:
Keepers: Diego López & Juan Carlos.
Defenders: Ángel, Marchena, Musacchio, Gonzalo, Capdevila & Catalá.
Midfielders: Bruno, Borja Valero, Senna, Cazorla, Cani & Jefferson Montero.
Strikers: Rossi, Nilmar, Marco Ruben & Altidore.
With Senna (and Montero) available, look for the typical starting XI:
Capdevila – Musacchio – Marchena – Ángel
Cazorla – Senna – Bruno – Borja
Rossi – Nilmar
Prediction: Villarreal drew last year at the Camp Nou, but Messi was still on vacation. Our 7-2-1 start is encouraging, but Barca's attacking trident is scary. If our back four and Diego López focus for 90 minutes, we can sneak a point, but it will be tough sledding. Endavant Villarreal!
