Serbia were defeated 2-0 by five-time champions Brazil at Moscow's Spartak Stadium on Wednesday, finishing this summer's tournament third in the group and failing to make it to the round of 16.

"We came to show what we are capable of. Serbia missed the [2014] World Cup and the [2016 UEFA] European Championship. We can be satisfied with the current result... We lost, but this is life. We couldn't beat one of the strongest teams in world football," Krstajic told journalists.

The head coach added that the team made mistakes in the Brazil clash, but he was grateful to players for their efforts.

"We shouldn't have lost concentration, playing against such a strong team. The individual ability of players comes to the fore in such moments. We made mistakes, and we were punished for it. I'm grateful to my team for the sacrifice they made. I think they gave it all to win," Krstajic said.

The 2018 FIFA World Cup kicked off on June 14 and will continue until July 15, with the matches being played in 11 cities across Russia.
