Spain coach Luis de la Fuente is delighted working with Barcelona midfielder Gavi.
De la Fuente is eager to work on honing Gavi's energy in the right direction during games.
He said: "Gavi is a player with many resources, versatile, useful all over... he feels more comfortable playing interior, but football can take you to other positions. He is a fantastic player at all levels. We haven't seen his best version of what he will be in the future.
"Gavi, in this process of maturity, one of the virtues he has is courage, genius and energy. However, he understands that now he is showing "some behaviours that are not beneficial for him and the team", although he has no doubt that "with maturity, he will understand that."
The Spain coach understands that time will put everything in its place, but he will spare no effort to ensure that Gavi's energy, which at some points may seem excessive, is managed in the best possible way.
He added, "We have talked about it and with the passage of time he will get it under control. Give me Gavi with this desire and drive, it's contagious for the rest."
