Spain bounced back from their Nations League disappointment with a 1-0 victory over Bosnia-Herzegovina on Sunday.
Brais Mendez's winner off the bench with 12 minutes remaining ensured Spain ended 2018 on a positive note, although their possession went amiss for large parts.
David de Gea had been roundly criticised for his display during La Roja’s 3-2 Nations League defeat to Croatia, and taking his place between the sticks was Kepa Arrizabalaga, whose €80m transfer to Chelsea in August saw him become the world’s most expensive goalkeeper.
Elsewhere, Espanyol centre-back Mario Hermoso debuted alongside Real Sociedad’s Diego Llorente in the heart of defence, while Rodri Hernandez and Suso joined Dani Ceballos in a new-look midfield.
Finally, Alvaro Morata was entrusted with spearheading an attacking trident that also included Real Madrid pair Isco and Marco Asensio.
The match came just hours after England beat Croatia 2-1 to deny Spain of a place in the Nations League Final Four.
Nonetheless, it was a celebratory occasion for ex-Roja midfielder David Silva, who was commemorated before kick-off, with the friendly being played in his homeland of Gran Canaria.
Isco and Suso had snapshots early on but failed to test Ibrahim Sehic in Bosnia’s goal, although Asensio spurned Spain’s only gilt-edged chance of the first half, sending a free header wide.
Alvaro Morata’s woes continued as he miscontrolled the rebound from a saved Asensio strike and ended up deflecting it wide from a yard out.
Nonetheless, Isco went on a mazy dribble and an unmarked Brais was at the right place at the right time to mop up Isco's parried drive on his senior debut.
