Verbeek is putting the finishing touches to his final squad of 23 to take to South Africa - and teenage dynamo Oar's impressive display last night has forced into possible World Cup contention.

The home side sealed its place in the 2011 Asian Cup when a squad made up of predominately A-League players downed the visitors through defender Mark Milligan's first international goal.

In what was a relatively uninspiring game of football where Australia justifiably went for substance ahead of style, the sublime skills and pace of Oar stood out.

Oar played the entire game on the left wing and his ability to take on defenders and deliver quality service to behemoth striker Josh Kennedy was especially noteworthy.

Verbeek did not attempt to downplay the 18-year-old's debut performance.

"I wish I could keep the pressure (on Oar) down a bit more, but I have to be honest, I think he played a fantastic game," Verbeek said.

"I could say that he didn't, or that he has a few things to improve on, but I think he was fantastic."

Oar completed a breakout season with the Brisbane Roar that saw him earn a national call up for Australia's Asian Cup qualifier against Kuwait in January, a game he ultimately played no part in.

Oar's slick skills and sudden rise has seen some pundits make comparisons with a younger version of Galatasaray maestro Harry Kewell, and he is set to join Feyenoord in Holland for a trial shortly.

Verbeek made a plea for the media to keep a lid on their great expectations, and admitted he was unlikely to make it into the South Africa squad on the back of one good game.

"Let's try and keep it normal for the boy - he's just 18 years old - don't mention him as the next Harry Kewell, please," he said.

"Let the boy just develop, he had a great year, and after a great year we all know it will be very difficult for him to stay at the same level."

Verbeek bristled when the inevitable question of whether Oar could be a bolter for the World Cup was raised.

"World Cup squad? The boy is 18 years old, he played one game in the national team, do we have to select him now do you think?" he said.

"If you're good enough, I don't care (about age), but after one good game, I don't think I'm going to say this is the next generation Socceroo, but I do hope so."

Verbeek did little to quash the impending speculation though, saying he was impressed with Oar's decision to opt for some trials in the Netherlands after the end of the domestic season.

"Never say never, let's be honest about that - he's going to have some experience abroad, that's perfect - very close to my place, that makes it even better," he said.

"So I can keep him under control a little bit and find out how he's going, and then, we will see."

The Asian Cup qualifier against Indonesia was the last international fixture for World Cup hopefuls to impress Verbeek before he names a 30-man squad for South Africa on May 11, which will be trimmed to 23 players in early June.

The manager was cagey when asked how many of those 23 spots have already been nailed down.

"How many spots are up for grabs? 23 as far as I can remember?" he quipped.

"Of course we have a couple of players that are good, and don't have that much competition, but there is two months to go, so a lot can happen.

"At this moment I have a minimum of three players for every position, and I'm going to find out more about them in the upcoming months.

"I'm going to travel around the world with the coaching staff to see all those guys play at club level, and then it's up to me to make a decision."

Verbeek was content with Australia's performance on Wednesday night, but admitted his side has plenty to improve on ahead of its opening World Cup fixture against Germany on June 13.

"We should have scored a few more goals to make everybody happy, but my job was to qualify for the World Cup, and to qualify for the Asian Cup, and we've done that now," he said.

"No disrespect to Indonesia, but I have an idea Germany will be a lot more difficult."

Indonesia coach Benny Dollo was a man of few words after his last game at the helm.

He said: "Indonesian football needs improvement, a lot of the players are now at the mature age and they need to improve."
