The La Masia product made his senior bow at club level in last month's 2-1 win over Getafe as a second-half substitute and has featured a further five times in all competitions.

At 17 years and 49 days, Gavi became the second-youngest player to make his full debut for the Catalans in last week's stalemate with Cadiz, behind only Ansu Fati (16 years, 318 days).

He is now in line to make his first appearance for Spain in next Wednesday's Nations League semi-final clash with European champions Italy at San Siro, with the winners of that match to face either Belgium or France in the final four days later.

Explaining his decision to call up the youngster, Luis Enrique said at a news conference on Thursday: "I like what I have seen from him. His level has surprised me.

"I have known about him for a long time as he's a player from La Masia. I have no doubt about his future performances.

"With there being players absent I can have a look at others. It's a shame for those who are not with us, but now others can join up.

"Gavi still has to improve, of course, but with and without the ball he can contribute to the side. Seeing what I have seen so far, he will be up to the task.

"It would be risky to put a young player in the side. Perhaps he has been called up too early, but he may still start against Italy. We will see if he can adapt to our side."

While Gavi is preparing to link up with the national side, fellow Barca youngster Fati has not been included by Luis Enrique having only just returned from a serious knee injury.

"It is a joy to see him back, and yes, with him playing again I wanted to bring him back, even if it was not to play and for him to just be with us," Luis Enrique said. 

"We have to put that situation in context, and right now the best option is that he is not with us and that he continues playing and adding minutes for his club."

Gavi is not alone in earning a first call-up to the senior squad as Yeremy is also included after scoring one goal and setting three up for Villarreal in five LaLiga games this term.

Only five players have been directly involved in more goals in the Spanish top flight this term, all but one of whom have played at least one game more.

Chelsea wing-back Marcos Alonso is also part of Luis Enrique's 23-man squad, earning his first call-up in three years, but there is no place for his team-mate Kepa Arrizabalaga.

Luis Enrique has once again overlooked Real Madrid's contingent of players, while Alvaro Morata, Gerard Moreno, Dani Olmo and Raul Albiol are nursing injuries.

Ander Herrera and Brahim Diaz, who have been in good form for Paris Saint-Germain and Milan respectively, are also left out.
