As many as 49 players have featured in Spain’s games since Luis Enrique’s appointment, but only 13 or 14 appear to have secured a permanent spot in the squad.
The goalkeeping trio of David de Gea, Kepa Arrizabalaga and Pau Lopez has remained intact, while Sergio Ramos, Sergio Busquets, Rodri, Rodrigo Moreno and Jose Gaya are also considered as vital members of the squad.
Meanwhile, Dani Carvajal, Jesus Navas, Jordi Alba, Saul Niguez, Dani Ceballos and Fabian Ruiz seem to have scored points with Robert Moreno in the last few games for La Roja.
If the 2020 European Championship were to kick off next month, there would be nine available spots in the Spain squad.
Following Gerard Pique’s retirement for the national team, several centre-backs have been used alongside Spain captain Sergio Ramos.
Although Sergi Gomez and Pau Torres were called up, they haven’t been used yet, with Diego Llorente, Inigo Martinez, Marc Bartra, Nacho Fernandez, Mario Hermoso, Unai Nunez and Raul Albiol all getting playing time in recent months.
Elsewhere, the four available full-back spots will be competed for amongst Carvajal, Navas, Alba, Gaya, Juan Bernat, Sergio Reguilon, Cesar Azpilicueta, Sergi Roberto, Jonny Otto and Marcos Alonso.
Dani Parejo could cover for Busquets or Rodri in the middle third, but Moreno also counts on Santi Cazorla and Thiago Alcantara, but not so much on Koke and Suso.
Rodrigo, Alvaro Morata and Paco Alcacer appear as Spain’s main No.9 options, with Mikel Oyarzabal, Pablo Sarabia, Luis Alberto, Jaime Mata, Gerard Moreno and Diego Costa being some of the alternatives in attack.
