Versleijen admitted the next match in the tournament was vital for his team’s future in the competition.

“It’s only the second game in the tournament, but it can be a deciding game,” said Versleijen. “The first game is important not to lose. Because, if you lose, you get more pressure on the second and third games.

“For us, the lesson we learned from our first game is that we have to work harder to keep the ball in the midfield.

“The main point for us is we have to get more control of the midfield which is what we lacked against Ecuador.

“We were lucky enough to get a point against Ecuador and that helped us a lot for the confidence and mood for our next game."

 Versleijen said he was taking nothing for granted in the match and respected the talent of the young Tico side.

"We know Costa Rica played a good game against Spain," he said. "They were very close to a draw, but in the end, in the last minutes they got three and then 4-1 against.

“What we also know about Costa Rica is that they are a technical, well organised group, playing a short passing game, who are able to penetrate into the penalty area and who are able to play one-v-ones."

Versleijen also hinted that there may be a couple of changes to his starting line-up for tomorrow’s match.

“Until now I haven’t told my line-up to the players so it’s a little difficult to tell here," he said.

“Probably I will make one or two changes to the line-up to the one that started against Ecuador.”

Although it was Tommy Oar who stole the headlines with his stunning free-kick against Ecuador, Young Socceroos goalkeeper Mark Birighitti also put in a fantastic performance and is looking to back it up with another solid match against Costa Rica.

“Overall I was happy with my performance against Ecuador, but I was disappointed that I couldn’t hold, or sufficiently push away, the shot that lead to the goal,” said Birighitti.

“Obviously my goal tomorrow night is to keep a clean sheet which will go a long way towards us getting the necessary points to progress to the next round.”

The Young Socceroos will play Costa Rica with kick-off at 11am AEST on Thursday, August 4, before their final group match against Spain at 8am AEST on Sunday, August 7.

The top two teams from each of the groups and the four third placed teams with the highest number of points will then progress to the round of 16 (August 9and 10). The Quarter-Finals will be played on August 13 & 14, Semi-Finals on August 17 with the Final and 3rd/4th place play-off on Saturday August 20.
