Spain have announced a 23-man squad for the Euro 2016 Qualifiers, which will be held in the first week of September. Spain will take on Slovakia and Macedonia.

Chelsea striker Diego Costa returned to the Spanish national side after almost a year's gap. Costa was struggling with his injury and that kept him away from his English Premier League and as well as his national side.

"Diego Costa was picked for sporting reasons, he wasn't in the best conditions. But he's overcome his physical problems and we have faith in him," Del Bosque told the reporters. 

Manchester United star goalkeeper David De Gea too has been named in this 23-member squad. De Gea has not featured in any of the games that the Red Devils have played in this ongoing season of Premier League, nor did he get a chance to guard the goals in the UEFA Champions League play-off games against Club Brugge. United manager preferred Argentine Segio Romero to De Gea, who Van Gaal felt is unsettled by interest from Spanish giants Real Madrid.

Spains' head coach Vicente Del Bosque has picked an experienced squad ahead of their fixtures against Slovakia on 5 September and against Macedonia on 8 September. Juan Mata, who has been in sublime form in this season for Manchester United was an obvious choice for Del Bosque. Costa's Premier League teammates Pedro Rodriguez and Cesar Azpilicueta have also been picked in this squad for the 2016 Euro Qualifiers.

"We can't experiment much, we want to start with a fixed group. These are two vital matches and we need six points to close in on the Euros," Del Bosque added.

Here's the Spain squad for Euro 2016 Qualifiers:

Iker Casillas, David de Gea, Sergio Rico, Juanfran, Dani Carvajal, Sergio Ramos, Gerard Pique, Marc Bartra, Jordi Alba, Cesar Azpilicueta, Juan Bernat, Sergio Busquets, Andres Iniesta, Koke, Santi Cazorla, Cesc Fabregas, Isco, David Silva, Juan Mata, Pedro Rodriguez, Paco Alcacer, Vitolo Machin, Diego Costa.
