Diego Costa has sent a legal document to the Brazilian FA to tell them he intends to play for Spain.
The Brazil-born forward, who plays for Atletico Madrid and took out Spanish citizenship in July, has been the focus of a tug-of-war between the two national federations since it emerged last month that he planned to switch allegiance from the country of his birth.
A paperwork issue reportedly stopped Costa, the current leading scorer in La Liga, from playing for Spain in their recent World Cup qualifiers.
Brazil coach Luiz Felipe Scolari has since called him into a provisional squad for his side's friendlies next month.
It now appears Costa is to stick with his intention to declare for Spain and, in a statement released on Tuesday, the Spanish FA said a legal document that would ensure Brazil no longer had any claim on the player had been drawn up and sent to CBF executive Julio Cesar Avelleda.
“This morning, Tuesday Nov. 29, the Spanish-Brazilian player Diego Da Silva Costa, Diego Costa, attended the notary Serrano 30, where he added his signature to a document that manifests his intention to play for the Spanish national football team,” it said.
“The forward has sent this document to Mr Julio Cesar Avelleda, secretary general of the Confederacao Brasileira de Futebol (CBF). It communicates his desire to be available for Spanish national coach Vicente del Bosque, from this moment.
“In this way, Diego Costa can play with Spain, in their next two games in November, if the national coach deems it opportune.”
It means Del Bosque is likely to include Costa in his squad for these games -- against South Africa in Johannesburg on Nov. 19 and Russia in Dubai four days earlier.
