#4: Gerard Pique
Gerard Pique has been Barcelona's main man in defence since captain Carles Puyol's retirement in 2014. Throughout his return from Manchester United back in 2008, the Spaniard has been a loyal servant to the club and an important presence in the backline.
Along with Sergio Ramos, with whom he has occasional spats, Pique has formed a formidable defensive partnership with the national team.
With the vast experience of playing against European heavyweights, Pique will be another man Valverde will be pleased to have in the squad. Pique also remains one of the seven players who have been a part of both treble-winning seasons at Barcelona.
