Bruno Fornaroli? I know he's 36, and no one is arguing he's first pick, but given all the injuries ... and he is top of the A-League goal-scorers?

And what about Nikita Rukavytsya? An article last month said he still hopes for another crack at the national squad.

Adam Taggart?

Searching through the cupboard for replacements.

Given McGree's injury as well.

TBH I would be tempted to have both Irankunda and Garang Kuol in the squad ... and to include Cummings to be included in a forward midfield role similar to Jackson Irvine. He is someone that will drop back to get the ball, links well with others a la Tulio, Kuol, Silvera, Nkololo at CCM last season, will chip in with goals and give the other attackers space to operate in.

Big downside though is that he is playing in the ISL.

McGree was listed on FotMob as coming back in Early December, so he'll probably get a decent number of games in this month. It depends on when Arnie has to nominate the squad 

If Duke can’t score vital goal/s like he did against Tunisia, could you really go wrong with G Kuol and Irankunda together as the top 2 instead? Bit green and both wildcards but both have the touch and technique to score goals against decent teams imo
