Frenkie de Jong is an undroppable player at Barcelona now, or at least he should be. The Dutchman has impressed in pre-season and it's clear that he is the best player they have in that position, leaving Sergio Busquets' place in the team at risk.

De Jong
De Jong is a breath of fresh air in the Catalans' lineup. He knows what he'll do before ever getting the ball and rarely puts a foot wrong. He has been excellent this summer.
Pique
Gerard Pique is ready to go. He has impressed this summer and did the same again against Napoli.
Griezmann
Antoine Griezmann is finding his feet and his partnership with Luis Suarez is falling into place. He marked his name on the scoresheet on Saturday.
Suarez
He wasn't in Japan, but that didn't stop Suarez from ending pre-season as Barcelona's top goalscorer.
Coutinho
Philippe Coutinho wants to prove himself this season and his appearance off the bench suggested that there is still some life in him. It would be great news for the Catalans
