Asked about who he is looking forward to seeing in the World Cup this summer, Gullit nominated two Barca players.
He told Marca: "Lamine Yamal, of course, is fantastic. I also like (Harry) Kane, you know, he scored so many goals. We'll have to see if he can do that with England, I don't know.
"I like Pedri, of course, and it will be fantastic to see Messi and Cristiano Ronaldo play in another World Cup. Mbappé is going to do very well too. Yes, I'm really looking forward to it. There are so many good players!"
On Pedri specifically, Gullit said: "Look, I don't think there are many players who have the same qualities. The most important thing isn't being a good player, but having the work ethic of a good player, and he has that.
"He works incredibly hard in midfield. That's why I like him so much. It's not just about what you do with the ball, but especially what you do when you don't have it."
