The 20-year-old was included in Luis Enrique’s squad for the upcoming games against Switzerland and Portugal as they wrap up preparations for the World Cup.
Nico, whose senior brother Inaki Williams, switched nationality to play for Ghana, in an interview with La Roja’s media staff acknowledged that he was not conscious he had made Enrique’s initial squad.
“I had no idea that I was in the pre-list, it has been a joy for my whole family and I am going to perform here,” he said.
“My parents and my whole family are proud of me and now we have to continue.
“I’m very happy to be here, I found out when the call came out. My feet on the ground, I want to work, for the coach to see me. I thank him for this opportunity and I’m going to give my best on the pitch.”
The winger might make his debut look when Spain face Switzerland of their fifth group game of the UEFA Nations League on Saturday, September 24.
