Sergej Milinkovic-Savic, whose non-selection during qualifying led to Slavo Muslin's sacking as Serbia coach, nearly broke the deadlock on the stroke of half-time, but his overhead kick was well kept out by Real Madrid 'keeper Keylor Navas in the Costa Rica goal.
"It is great to have three points, but we are not finished".
The wall of noise and colour from outside the ground was soon transported indoors, where the nearby Costa Rica fans in particular made it hard to hold a conversation with a colleague sat three yards away.
When Serbia were on the ball, the 23-year-old found space alongside Aleksandar Mitrovic in attack, switching the formation to a 4-2-4 at times using his height and power to become a nuisance to the defenders winning four of his aerial duels while also creating three chances. Kolarov and company still have two more tricky group stage fixtures against Switzerland and Brazil.
The captain added that Costa Rica hoped to show on Sunday that they had learned from their mistakes. Kolarov capitalized on the opportunity, curling the free kick past Navas' reach.
ROK official: No change to U.S. troops in S. Korea
The US has stationed combat troops in South Korea since the Korean War ended in 1953 with an armistice and no peace treaty. However, the parties agreed to continue to work on finding solutions on these issues, said in a joint press release.
Meanwhile, Costa Rica boss Óscar Ramírez spoke defiantly after his sides loss, claiming that the World Cup is far from over for his side despite the defeat.
Goals are of course what everybody watching that match will be wanting to see scored, and this is going to be a very tricky match to call, if you are trying to get your head around which team is going to win.
"I'm friends with Kolarov who scored an unbelievable goal today, and (Nemanja) Matic, these guys", he said.
