Luis Enrique believes Gavi will become one of the "stars of football" after the teenager scored his first World Cup goal as Spain thrashed Costa Rica 7-0 on Wednesday.
Gavi netted the fifth goal in a one-sided clash, getting on the end of an Alvaro Morata pass to fire in off the right post with 16 minutes remaining.
Aged 18 years and 110 days, it made him the youngest player to score at a World Cup for any nation since Pele (17y 249d) for Brazil in the 1958 final against Sweden.
At a press conference after the Group E victory, La Roja head coach Luis Enrique was asked just how good the Barcelona midfielder can be.
"I don't know, I hope he's going and playing every time better and trying to be aggressive with and without ball," he said.
"He's unique, very different because he's 18 now, but he has the personality of an experienced player.
"It is a pleasure to play with the boy, because he is a boy. He needs a bit of calm sometimes but we are very happy to have him in the team.
"I think he's going to be one of the stars of football."
Sunday will see Spain's second game in Qatar against Germany, who were surprisingly beaten 2-1 by Japan earlier on Wednesday.
