Ansu Fati can play in the Clasico on October 26 after the Spain U17 team did not call him up to play in the World Cup in Brazil.
Ernesto Valverde, who had shown hope that the 16-year-old forward would instead go with the U21 side, will not lose the youngster now for the showdown with Real Madrid at Camp Nou.
That could be crucial as Ousmane Dembele has been handed a two game suspension which keeps him out of the match against Barca’s bitter rivals.
Jose Martinez and Ilaix Moriba from Barca’s youth categories were picked by coach David Gordo.
The RFEF is working to close the bureaucratic issue with FIFA which stopped Spain U21 calling up Ansu for this international break.
