Alex Brosque? When does his contract expire? End of this year or early next year?
Wont be Brosque either. He's signed on to Sydney and they definately wont let him go.
It can only be Mrdja or Kwasnik imo. Lawrie has said he would probably keep Mrdja for another year on a heavily reduced contract, so that leaves Kwasnik. (who is also signed on for another season at CCM, but I can see Lawrie letting him go)
Yeah, there are not many players still not contracted for next season. Here is a list from the Sydney FC forums, so can't guarantee accuracy

CCM:
Contract expires end of season three:
#4) Ian McAndrew
#9) Nik Mrdja
#15) Andrew Clark
#17) Matthew Osman
Perth Glory:
Contract expires end of season three:
#1) Jason Petkovic (wants to play on, Mitchell still undecided)
Queensland Roar:
Contract expires end of season three:
#20) Matt Ham
Any other targets would have to be released. CCM have Caceres and El**ch which could make Kwasnik surplus to requirements. I don't see Brosque going anywhere and would fit in a 433 with Aloisi and Bridge. So it is slim pickings if we are targeting a current A-League player.
