The Socceroos are a different beast to Ange Postecoglou's team that beat South Korea in extra time to lift the trophy on home soil in 2015.
They have a new coach in Graham Arnold and a mostly inexperienced squad, with the majority of the 23 in the United Arab Emirates never having experienced the cut and thrust of Asian Cup football before.

The Socceroos have been hard at work with head coach Arnold putting his players through their paces. They sounded an early warning to their rivals after securing an emphatic 5-0 victory against Oman in a warm-up tie in Dubai and would be keen to continue from where they left off.
China too have been working hard as Marcello Lippi's players have undergone several training sessions since arriving in the UAE.
Iraq have also arrived as the West Asians look to replicate their title-winning form of 2007. Having finished fourth four years ago, Iraq will definitely be a team to watch out for in the AFC Asian Cup UAE 2019.

The Taeguk Warriors are consistent performers at the AFC Asian Cup, having taken four runners-up and four third-place finishes and last time they almost came close to winning it before faltering in final to Australia.
It's all systems go for the AFC Asian Cup UAE 2019 with teams having touched down in the four cities that will host the continental showpiece.
