Samara, Russia, Serbia beat Costa Rica by 1-0 in the opening World Cup Group E match in the Samara Arena on Sunday.
Captain Aleksandar Kolarov in the 56th minute scored a goal and secured a 1-0 victory for Serbia.
The defender hit the ball with his left foot and into the top right corner of the net past an outstreched Keylor Navas to break the stalemate after an evenly-matched first half.
Costa Rica, had earlier reached the quarter-finals in 2014, struggled to make chances for an equaliser as Serbia shut down their attack and came close to scoring again several times.
Serbia have won their opening game at a World Cup tournament for the first time since 1998, when they did so as Yugoslavia against Iran.
