Verbeek has admitted that a lack of experience is counting against the former Brisbane Roar winger, who swept into calculations after a stunning debut against Indonesia in an Asian Cup qualifier in March.

Since then, he has made a move to Utrecht FC in the Netherlands and his performances there have Verbeek believing he can make the grade for the World Cup.

"If you look at his experience, then there's no chance because he's just coming out of the A-League and is 18 years old," Verbeek said.

"On other hand I don't pick players just because they have beautiful blue or dark eyes and they're such nice guys. I pick a player because I think he can be part of the selection and Tommy has something special.

"He showed it against Indonesia, he showed it in the two weeks in the Netherlands, they were all impressed about him. Tommy can show us that he can be part of the last 23. He has the talent, he's left-footed and we don't have so many in that position."

Oar admits his selection as one of the final 30 came as a complete surprise, but he is ready to take his chance and press his case.

"I'm very proud obviously. To get the phone call was a great moment," he said. "I didn't know what to expect. I wasn't really getting my hopes up, but I was waiting for that final call to see what happened.

"I was very happy. I'm just looking forward to the experience at the training camp and hopefully working hard and getting into that 23."

Oar is now faced with the most important two weeks of his footballing career, with a five-day Socceroos training camp followed by the farewell match against New Zealand at the MCG on May 24. The 18-year-old sees that match as crucial for fringe players like himself to press their case for inclusion into the final squad.

"I think it will be important to everybody. It's our last preparation match before he selects the side, so obviously it will be in the back of his mind how people perform in that game. Everyone will be up and firing for that game, trying to press their case," he added.
