Versleijen knows that only a win would guarantee his team passage to the Round of 16 and he believes they have the game plan that just may do the job.

“We are feeling quite confident because it is actually a clear task,” said Versleijen

“You have to win, there is nothing in between, and that makes the assignment that little bit more easy to do. Not easy on the field. But it is clear for everybody and the players understand it.

“Today we had a training session. We tried to prepare to play a good game against Spain knowing that we have to win the game.

“We will start very offensive and we will try to put some pressure on Spain from the start and hopefully that will give us an early goal.

“We have some more scenarios if we are leading what we are going to do, also when Spain is getting in the game what kind of things we have to do.

“So hopefully all the game plans we have will be sufficient to get a good result against them."

Versleijen is very aware that a difficult challenge awaits his team tomorrow evening.

“But it will not be easy," he said. "It is clear that Spain is the best team in our group and they proved it with both games they play especially the first game against Costa Rica when they played really nice football.

"Against Ecuador, until Ecuador had the send-off, it was an even game, but after two minutes already they scored the goal.

“You try to start from the beginning. The beginning is when the goal keeper has the ball. So you don’t give them the chance to build up from the back and that is our main approach.

“That’s easy to do because that’s almost like a standard situation, you can organise that very well. The more difficult part is the moment we have the ball in certain parts of the field, we lose the ball, what do you do then?

"But that’s a more difficult part because that’s not always something you can control. Our aim is to press them from the start. Don’t let them build up from the back. Don’t let them get into their game."

When asked about whether he thinks Spain may rest some players, in particular the players on yellow cards, having already topped the group, Versleijen was not convinced that that would be an advantage.

“That will probably happen (resting players). For sure the number 6 (Oriol Romeu) will not be play because he has two yellow cards," he said.

“But that’s not always an advantage. If you play against the players who have already played two games they also have a little bit of tiredness and they’re also already thinking about their next game, having already qualified for the next round.

“The new players coming in have something to prove because that’s their chance to get into the team. So it’s not always an advantage. But again it’s up to us, how good we are and what we can do against the combination play of Spain."

One of the changes that Versleijen has been forced to make is to field a suitable replacement for the team captain, Ben Kantarovski, who is suspended for the match having collected two yellow cards in the previous two matches, but who was also a very influential player in those matches.

"It was questioned how we can take a player (Ben) who came from a severe injury, but he proved until now that he is an important player in our team. Although we know he can do even better, but that is only something that you can improve with time," he said.

“The reason that he is playing is because we don’t have someone with this specific quality like Ben has, but we will find a solution for tomorrow’s game."

Versleijen’s final words hinted that there may be a few more changes in the wings.

"We will change some things. First of all we have to change because of Ben. We also change because we have to bring in some more power up front," he said.

With Ben Kantarovski suspended, Versleijen also announced that the captain’s arm-band will be handed to Young Socceroos goalkeeper Mark Birighitti who is having a fantastic tournament and who also captained the team against the Korea Republic at the pre-tournament training camp in Denver.

Birighitti was honoured to be called upon to lead out his country in such an important match.

“To captain any team is an honour, but to captain Australia at a World Cup against a team like Spain will be an extra special honour,” said Birighitti.

“We know the challenge that lies ahead, but all the boys are mentally and physically prepared to do the job at hand."

The Young Socceroos will play their final group match of the U-20 World Cup Colombia 2011 against Spain on Saturday 6 August (kick-off 5pm local, 8am AEST Sunday 7 August).

Although a win will guarantee the Qantas Young Socceroos passage to the next round, following today’s results, there is a chance that the Young Socceroos may also progress to the Round of 16 with a draw against Spain if Ecuador does not defeat Costa Rica in the other group C match.

The Young Socceroos matches and the Semi-Finals and Final of the FIFA U-20 World Cup Colombia 2011 will be broadcast live on SBS TV.
