Sydney FC coach Vitezslav Lavicka is confident the club will retain two key players as they strive to make the Australian World Cup squad. In-form striker Alex Brosque and defender Simon Colosimo may seek loan deals in January so they can continue playing once the A-League season finishes in March to retain fitness and form but Lavicka believes his players "We know Alex and Simon are playing for the Socceroos but we are going to keep them and keep going this season," said Lavicka.

"We have a serious (chance) to have good success this season and the players want to play for Sydney FC.

"It's no problem for us. I think they won't ask us (for a release).

"We (will) help them after this season (to have a) good preparation before the World Cup."

Sydney captain Steve Corica said Brosque, who is currently in career-best form, would be pretty keen to hang around at the Sydney Football Stadium to help his teammates in their championship pursuit.

"He doesn't want to go. Obviously he wants to go to the World Cup but he wants to stay until the end and see the season out," Corica said.

"It's a tough one but he's said himself he wants to stay until the end and it's important for us to keep him. If he does well and he wins the championship with Sydney that's going to help him as well.

"They (Brosque and Colosimo) want to do the best for the club. They want to win something.

"The World Cup is important as well - everyone wants to play in a World Cup - and both of them would love to be in the squad.

"But who's to say if they go in January that they'll be in the squad?"
