Bryan Zaragoza, who plays for Granada, was surprised by Casado's performances with La Roja and called him an "animal."
“He’s an animal. I don’t even know what to say about how he played. He's barbarbic," Zaragoza told reporters on Monday (h/t SPORT).
Yeremo Pino also provided his thoughts on the youngster: "He's a machine. He's given a recital, he's already shown his quality at Barca and now he's done it with the national team.”
Lastly, coach De La Fuente also showered Casado with praise and admitted he was surprised by how quickly the midfielder adapted to the international game: “It was impressive how he played in a game and a half with the team, he looked like a veteran for the way he read the game."
