Serbia's captain Aleksandar Kolarov and midfielder Nemanja Matic are considering their international futures after a 2-0 defeat by Brazil eliminated them from the World Cup.
"I will speak with the people from the football federation, whether they see me in the national team," Kolarov, 32, was quoted as saying by Blic newspaper. "If I can't contribute to what the national side needs, I won't be selfish.
