The 64-year-old was the subject of a prank on Spanish radio, where the coach unwittingly revealed that attacker Fred would be ahead of Diego Costa - should he opt for Brazil
The 64-year-old was contacted by a member of the comedy troupe 'El Group Risa', who claimed he was Atletico Madrid president Enrique Cerezo, with the call broadcasted on Spanish radio.
Speaking on the show El Partido de las 12, Scolari confirmed he could bring the 25-year-old to the World Cup, but may have scuppered his own ambitions after revealing he would be behind Fred in the pecking order.
"If the World Cup was today I would bring him to Brazil," Scolari said. "I like Diego. The first choice is Fred, who is injured at the moment. Diego is the second, and I need to look for a third."
The Rojiblancos hitman has been the subject of a tug-of-war between Selecao and la Roja for the striker's allegiance in recent weeks - the latter of whom are believed to be the player's preference.
Reports emanating from Spain on Thursday have suggested that the Brazilian Football Confederation (CBF) has called up Costa for the friendlies with Honduras and Chile next month.
If reports are true the in-demand star will have until Oct. 31 in which to either accept or decline the invitation. Failure to respond in the allocated time frame would result in an obligation to join up with the Selecao.
The Brazil-born marksman has already represented his country of birth on two occasions - both friendlies - but is now eligible to switch loyalties to la Roja having earned Spanish citizenship through five-year residency.
Costa said after Atletico Madrid's victory over Austria Vienna in the Champions League that his decision has been made regarding which country he will play for, though, he has not revealed who he has selected.
Scolari's men face Honduras in Miami on Nov. 16, before facing Chile in Toronto three days later.
