The Perth Glory custodian accepts the Olympic Games is a huge shop window for young players and many a career has been made on the back of a good tournament.

However, Velaphi feels the best way for players to boost their chances of going on to bigger and better things is to be part of a team that people will remember.

Speaking ahead of the Olyroos next warm up game against Japan on Thursday, Velaphi, who is of Japanese and Zimbabwean parentage, said: "It's a massive tournament for everyone. It's the second biggest event (outside of the World Cup)."

Velaphi said it was now about the team achieving the best possible outcome at the tournament rather than focusing on post-Olympic career ambitions.

He said: "You can't look at things individually."

Velaphi played in the 1-0 defeat by China at the weekend but with Adam Federici having now arrived from England, he knows he must keep working hard to hold on to the jersey.

"Feders is a great keeper and whoever gets it we will support each other 100 per cent," he said.

Velaphi admits it is a bitter-sweet scenario with Danny Vukovic having been thwarted in his bid to reach Beijing but the Glory keeper was delighted to receive the backing of his former rival and friend.

He said: "He wished me good luck and said to enjoy it."

Velaphi revealed that the players would be fighting fit for the start of the Olympics with the squad being worked hard.

He said a busy program of warm up games had been welcomed by the players. He said: "It's Japan next, another quality opponent. I think we have played 14 or 15 games since we qualified."

Teammate Kristian Sarkies joked over the weekend that he was looking to scare goalkeepers with the unpredictable flight of the tournament ball.

Velaphi agrees that the ball certainly moves about in the air but that it was the same for both sides.

The Olyroos take on Japan Under 23s on Thursday night. Kick off is 8pm AEST.
