Sydney FC could be boosted by the return of leading strikers Alex Brosque and Bruno Cazarine for Sunday's clash with league leaders Brisbane Roar.

The Sky Blues were without the pair, who are joint leaders on the team goalscoring list with six, for last weekend's toothless 4-0 loss to Central Coast Mariners but they are close to taking on the Roar at Sydney Football Stadium.

"My groin isn't too bad at the moment. It's not the greatest but I've trained the past week with [strength and conditioning coach] Craig [Duncan] and just have been slowly building it up but tomorrow is the real test,'' Brosque told the Herald. ''I'll join in with the boys for full training and if I pull up well then I'll be right to play. I won't really know where it stands until I test it completely but, in my head, I'm playing - or at least putting my hand up.''

On the fitness of Brazilian forward Cazarine, Brosque was far more optimistic.

"He seems well and he trained as normal this week and got through some really tough sessions,'' Brosque added. ''I'm pretty sure Bruno will be fine to come straight back.''

Sydney will be desperate to get a favourable result against the high-flying Roar to keep their finals chances alive.
