Spain will take on Portugal in an international friendly on Friday night, with Luis Enrique's side building towards the start of their Euro 2020 campaign against Sweden on June 14.
Enrique controversially left Sergio Ramos out of his squad for this summer's competition, and it is going to be fascinating to see how La Roja line up for their first Group E fixture.
Robert Sanchez is one of two uncapped players in the Euro 2020 squad, but it has been widely reported that the 23-year-old will be given the nod between the sticks for this match.
Marcos Llorente and Jordi Alba are expected to be the two full-backs, while Eric Garcia and Pau Torres could line up in the middle of the defence.
Sergio Busquets and Koke could be joined by outstanding Barcelona youngster Pedri in midfield, while Gerard Moreno - off the back of an excellent season for Villarreal - should lead the line.
The other two positions in the final third are certainly open, but Ferran Torres has become an important player under Enrique and should therefore feature, while Mikel Oyarzabal may get the nod on the opposite side.
This match provides an opportunity to have a look at a number of different things ahead of Euro 2020, and there should be a first cap for Aymeric Laporte, who has declared for Spain over France.
Adama Traore will also hope to be involved in some capacity, while Thiago Alcantara, Rodri and Fabian Ruiz are options in what is a very talented midfield group.
Spain possible starting lineup: Sanchez; M Llorente, Garcia, P Torres, Alba; Koke, Busquets, Pedri; F Torres, Moreno, Oyarzabal
