Atletico Bilbao forward Nico William has discussed his decision to choose Spain rather than Ghana.
In the UEFA Nations League encounter against Switzerland, the 20-year-old made his debut for Spain.
The striker entered the game when Spain trailed Switzerland 2-1 in the 63rd minute.
"It's the biggest jump of my career. I am grateful to the mister for the trust and you have to go to Portugal. He has asked me to do what I do at Athletic, to face and do one on one," Williams said after making his debut for the 2010 World Champions.
Nico, who could have played for Ghana because of his parents, chose to play for Spain.
The Ghana FA was successful in persuading Inaki Williams, his elder brother, to change his nationality, but was unsuccessful in their efforts to persuade Nico Williams.
Inaki Williams made his international debut for Ghana against Brazil, and Nico played for Spain against Switzerland.
Reacting to why he opted to play for Spain, despite Ghana FA making approach, he said, "I have always been clear that I wanted to be here and I am very happy that Luis Enrique has given me this opportunity, I hope to take advantage of it. As everyone knows, I want to be with the Spanish team and be better, show that I'm worth being here".
Nico Williams will be vying for a spot on Spain's World Cup team in 2022.
