Spain U17 manager David Gordo wants to bring FC Barcelona striker Ansu Fati into his squad for the U17 World Cup squad.
The tournament kicks off in Brazil in October, and Gordo wants Fati in his squad and he confirmed the RFEF are working on a deal to naturalise the Guinea-Bissau born teenager.
"I have not spoken to him, but I know that he wants to play for Spain.
"We are all in agreement and are confident that the situation can be sorted.
"Our preliminary list will be submitted to FIFA for the World Cup on September 25, and I hope Fati will be in it.
"We know that he has the possibility of representing Guinea-Bissau, but we are hopefully of agreeing a deal for him to play for Spain."
Currently, Fati does not meet the requirements for Spanish citizenship, as he has only lived in the country for eight years, not the required ten.
Reports in Spain claim that his father could apply for citizenship, allowing Fati an alternative route to qualify for Spain.
