The uncertain futures of veterans Tim Cahill, Mile Jedinak and Mark Milligan mean there's likely to be personnel changes.

As well Australia's failure to score in open play in three matches has to lead to changes in attack, which must be a big focus for Arnold immediately.

So we've decided to take a look at seven possible newcomers for the Asian Cup.

Adam Taggart (Brisbane Roar)

The 25-year-old striker has fallen off the international radar since playing at the 2014 World Cup, after an injury-cursed stint in England. He couldn't shake off the injury issues at Perth Glory but still managed 20 goals in 40 appearances which is a decent return. If he can find fitness and regular goals at Brisbane, he's every chance to return to the national set-up given he's still only 25 and there's few Aussie forwards who tick those boxes.

Chris Ikonomidis (Lazio)

Long hailed as the next big thing, Ikonomidis reminded us all of his potential with an impressive loan stint with Wanderers last season, scoring three goals in 10 games and setting up a few others. The 23-year-old winger has opted to return to parent club Lazio, where he's unlikely to see first-team action, but a loan stint elsewhere in Europe could see him catapult back into the national frame, given his attacking quality.
