The defender captained his country at last year’s World Cup but, after losing the captaincy to Neymar, has now been left out of Brazil’s last three squads.
Brazil face Peru on Tuesday without David Luiz after he was sent off in the 1-1 draw with Argentina on Friday, leading local media to call for Silva’s return – but Dunga shrugged aside questions over a possible return for the 31-year-old by insisting he preferred to discuss players who made his squad this month.
“In my view, this answer is that there is no value in discussing a player who is not here. And, especially in games for World Cup qualifying, let's focus on those who are here,” Dunga told a press conference on Mondau.
The suspension of David Luiz, who was replaced in the squad by Atletico Mineiro’s Jemerson, means Corinthians stopper defender Gil is likely to partner Miranda in central defence.
Luiz’ and Silva’s club-mate Marquinhos would have been in line to deputise against Peru but he was forced to withdraw from the squad through injury earlier this month.
And Dunga has challenged Gil to adapt the system already in place, insisting the enforced change to the back four will not have any significant impact on the team’s style of play.
“The playing style remains the same,” he said.
“There is a difference in the characteristics of the player, but it is up to him to adapt to the his team-mates. The squad has their style of play.”
Thiago Silva has appeared in just seven of the 20 games Dunga has overseen since the World Cup.
Brazil, who have earned four points from their opening three qualifiers, host Peru at the Arena Fonte Nova in Salvador.
