Asked in a quickfire round of questions which national team player he would sign for Barcelona, the midfielder gave an honest answer.
"(Marc) Pubill, I like him. No, look, I'm not going to say Pubill, I'll say Oyarzabal. And from the World Cup? Julian Alvarez," Gavi said.
The Atletico Madrid striker has long been one of Barcelona's most coveted targets in the transfer market.
Gavi also reflected on Marc Cucurella's surprise move to Real Madrid, admitting the Spain squad only found out the day before it was announced.
"We found out the day before, after training, and honestly we weren't expecting it. The bastard kept it quiet. Nobody knew," Gavi said. "Of course there's been banter — Lamine winds him up sometimes. Now he'll have to defend Lamine in the Clasicos: that'll be fun. I like Cucu as an opponent: he's a nuisance, he's intense. It's a good signing for them; I was happy for him."
Gavi suggested Real Madrid's revolving door at full-back only highlights the value of having one of the world's best wide players on his own side.
"I think they've changed full-backs a lot over the years, but that's what happens when you have the best on our side: he's very difficult to stop, and I hope it stays that way," Gavi said. "I'm more than ready. I'm very motivated and I love all of this, so it's good for football in general and people are going to love it. So yes: we're ready."
Asked about Spain's underwhelming display in a goalless draw with Cape Verde, Gavi said the criticism that followed had not caught him off guard.
"I already expected it. Since my debut I've always been a player who gets criticised, and honestly, I've never let it get me down," Gavi said. "It's not that I like it, because obviously I don't like receiving it, but it's something that motivates me even more. People don't know about football. They focus on silly things, on assists, on goals. For me, football is much more than that. If you're on my team you love me; if you're not on my team you probably want to kill me."
