Nick Carle insists Sydney FC's star-studded combinations will improve with every game as the Sky Blues look to fuse marquee signing Brett Emerton into a new-look squad.

Sydney coach Vitezslav Lavicka's decision to play Emerton in a wide left role for much of Saturday's 2-0 loss to Brisbane Roar has come under question in recent days, with calls for the Socceroos star to be used more centrally.

Lavicka is still juggling with his best set-up with Emerton's arrival, the return of Slovakian midfielder Karol Kisel and a squad brimming with attacking talent in Karle, young gun Terry Antonis, Terry McFlynn, Mark Bridge and Bruno Cazarine.

But Carle, who has been used up front in Sydney's opening two matches, felt Emerton was versatile enough to play anywhere on the pitch and said the squad simply needed time to build combinations.

"I think that was the first time we've fielded that team, so it's obviously going to take a few games to gel and mould," Carle said.
