It's been a long and at times frustrating wait, but opportunity knocks for Stuart Musialik this weekend, with the midfielder set to feature in the battle with Branko Culina's boys.

Musialik played for Sydney's National Youth League side against the AIS last weekend but now he is craving the A-League stage.

"I have been waiting a long time.  I'm looking forward to it and (I'm) keen to take it with both hands," said the 24-year old. "I'm not really fussed about who we're playing against.  It's been a very frustrating time for me lately and I'm just happy to be out on the pitch and it doesn't bother me where it's at or who it's against, I just want to get out there."

With three young members of Sydney's senior squad away preparing for the FIFA U20 World Cup in Egypt and injury concerns hanging over a number of other players, Musialik isn't likely to be the only new face in the Sky Blue lineup this Sunday.

"We are thinking about some changes, because Young Socceroos go to the World Cup and we have some injury problems," said coach Vitezslav Lavicka. 

 "We have Adam Casey and Stuart Musialik, they wait for the chance to play and now the opportunity is open for them."

Having waited so long for his opportunity, Musialik is determined to rise to the challenge laid down by his Czech mentor and help Sydney snap a two game losing streak.

"At training they have been talking about having a bit more patience, and that's part of my game - knocking it around and keeping possession," he said.

"We've had the two losses and they're (Newcastle) coming off a big loss from last week so both teams definitely need a result this weekend to get the ball rolling again.  It's a big game for both of us and hopefully we can get the three points.

Coach Lavicka added: "We lost the last two games but now we have the good opportunity to show that as a team we have good, strong character. 

"They (the players) are hungry to be better than last week."

Sunday's A-League clash kicks-off at the Sydney Football Stadium at 3pm, following the National Youth League curtain-raiser between Sydney FC and the Jets.
