Branislav Ivanovic becomes Serbia's most capped player in Costa Rica match

"It was an awesome goal", Costa Rica defender Bryan Oviedo said of Kolarov's effort.

Serbia finally got a break in the 56 minute after David Guzman was shown a yellow card.

Despite having only four caps to his name, the 23-year-old looks set to start in a midfield three with experienced pair Nemanja Matic and Luka Milivojevic in the Group E clash in Samara.

Kolarov downplayed the defeats suffered by Costa Rica in the pre-World Cup friendlies against England and Belgium.

"Regarding Switzerland, we have analysed all three opponents and how they have played over the past few months", Krstajic said.

Coach Ramirez faces the task of rallying his players before they play five-time World Cup winners Brazil in St. Petersburg on Friday. With Brazil and Switzerland, the other two teams in the group, the result of this game is of great significance to both sides as the loser is highly unlikely to make it to the next round.

"The match against Switzerland is going to be the most hard one", he said.

Arsenal forward Joel Campbell looks likely to leave the club this summer, but is not letting stories of an exit distract him from the World Cup.

Serbia's stout defense, led by Kolarov, who plays for Roma, and veteran Branislav Ivanovic, a former Chelsea player who was making his second World Cup appearance, proved a difference in the match.

We have been treated quite well in the early stages of this World Cup.

Milinkovic-Savic gave Navas a workout in the first half, and while he didn't score, he is clearly a potent weapon for Serbia.

Bunjevcevic suited up in 16 games as defender for the national team from 1998 to 2003.

Serbia also have a dynamic midfielder in Sergej Milinkovic-Savic, who is coming off a fantastic season with SSC Lazio in the Italian Serie A.

As Serbia celebrated its 1-0 victory over Costa Rica in the World Cup on Sunday, the celebratory mood briefly turned somber.

With Costa Rica proving a tough nut to crack, Kolarov stepped up to bury a 25-metre effort from wide on the right, lighting up an otherwise tight game in the southern Russian city of Samara. "Now we are going to watch for some details in their match with Brazil to see if we missed anything".
