Promising striker Nikita Rukavytsya says he is just happy to be a part of the Australian World Cup squad.

The 22-year old is one of 28 men in South Africa preparing for next month's tournament and knows he has plenty of hard work to do if he wants to play a key role in the Socceroos campaign.

Rukavytsya, who spent part of last season on loan with Belgian club Roeselare from Dutch champions FC Twente, is a good chance to play some sort of role off the bench as an attacker but insists he is just happy to be there.

"I'm not really worried about that, I'm just happy to be part of the team," he said.

"If I get a chance obviously I'll do my best to help the team achieve whatever we want to achieve.

"Every day's important, even training, everybody's fighting for the positions and training's intense, so we've got to see what happens.

"I've just got to work hard and show that I'm ready and we'll see what happens."
