Spain will be looking to book their place at Euro 2016 when they host Luxembourg at Estadio Las Gaunas on Friday.
Vicente del Bosque's men lead the way in Group C and will secure a spot in next year's tournament in France should they take all three points against their 142nd-ranked opponents in Logrono, La Rioja.
"I was at home and was very excited when I got the call. It's a surprise. I didn't expect it," he said in a press conference.
"I'm happy the coach has placed his trust in me and I'm happy to be in the squad.
"It has come as a 27-year-old. I've had to work hard for this.
"Of course I want to [debut]. I'll try to do everything right during the week to get the chance.
"Hopefully I can be at the [Euro 2016] tournament. I am aware that I am here due to an injury, but I will try to be there."
A ban also rules Chris Philipps out for Luxembourg, with Luc Holtz's men having nothing to play for after picking up just four points from eight fixtures in this qualifying campaign.
