Sky Blues striker Aloisi, who will make his 50th A-League appearance this weekend, has been declared fit after a hamstring scare and is expected to start against Brisbane Roar.

"We want to finish top of the league so really we have to win all three remaining games to do that. So this is an important game for us," Aloisi said.

"It's going to be pretty open if they come out and try and win the game. It could play in our favour because it'll be an attacking game and as a striker you like attacking games and open play.

With Mark Bridge unavailable through injury, Aloisi is keen to build on his goal tally for the season.

"It's been good to get playing again, get regular game time. I've been happy with the recent form and hopefully I can continue on into the finals," he said.

Despite Roar's recent form, having only gained one point from their past four games, Aloisi recognises the threat they pose.

"I expect them to be up for this game. They have got some older pros that work really hard, especially the ones in the midfield like Matt McKay and [Massimo] Murdocca and then they have young players like Tommy Oar that want to prove how good they are," Aloisi said.

"We know they've had their problems but we just have to concentrate on our game and not worry about their game."

The head-to-head ledger stands at one apiece this season, with each side claiming home wins - Brisbane 1-0 in round 8 and Sydney FC 2-1 in Round 12.

"We expect a tough game over there because they play good football and they also have a chance to reach the top six," coach Viteslav Lavicka said.

"I have a good feeling from our players. They are hungry for success."
