Uzbekistan, Indonesia, Iraq, Syria

Uzbekistan will be determined to lift the title on home soil but will first have to overcome a stiff challenge from their Group A opponents who will also fancy their chances of advancing to the knockout stage.

The hosts, however, will be buoyed by their form in Group A of the Qualifiers, which they competed in for exposure.

Impressive wins over Maldives (7-0), Myanmar (3-0), Saudi Arabia (2-1) and China PR (2-1) - coupled with home ground advantage - certainly makes 2008 runners-up Uzbekistan a force to be reckoned with.

Indonesia, whose only title triumph was in 1961, were equally impressive in the Qualifiers, topping Group F with three wins as they finished ahead of Vietnam, Timor-Leste and Hong Kong. 

Syria, champions in 1994, and five-time winners Iraq advanced to the Finals as among the best five runners-up, finishing second in Groups D and H respectively. 

The Finals, however, will be a different ball game altogether and all four teams know there will be no room for error if they want to challenge for the title.

Qatar, Australia, Vietnam, IR Iran

Another tough looking group which has two former winners in Islamic Republic of Iran and Qatar, 2010 runners-up Australia and 2016 semi-finalists Vietnam.

Qatar were perfect in Group B of the Qualifiers as they cruised to wins over Nepal, Bhutan, Bangladesh and Bahrain, scoring 14 goals and conceding just once.

Islamic Republic of Iran were equally impressive, topping Group J with nine points while Australia didn't put a foot wrong either in Group H, also registering three wins.

Vietnam are the odd ones out, sealing their place in the Finals as among the five best runners-up after finishing second in Group F. 

The Southeast Asian side, however, have become a force to be reckoned with at all age-group levels and fans can rest assured there will be no easy matches in Group B. 

Korea Republic, Tajikistan, Jordan, Oman

Champions 12 times, runners-up five times with a total 27 top-four finishes in the 40 previous editions of the tournament make Korea Republic favourites to advance to the quarter-finals from Group C. 

Their form in qualifying was impressive, with emphatic wins over Sri Lanka, Mongolia and Malaysia sealing them the Group E top spot. 

While Korea Republic's Group C opponents cannot match their rich history, Tajikistan, Jordan and Oman will be up for the challenge. 

Tajikistan, quarter-finalists in 2016 and 2018, topped Group I of the Qualifiers while Jordan, who failed to advance to the knockout stage in 2018, emerged the Group D winners.

Oman overcame a 1-0 defeat to Afghanistan to win Group G ahead of Thailand and will be counting on the experience gained from the hard-fought Qualifiers to power them into the knockout stage for the first time in their third appearance in the Finals.

Saudi Arabia, Japan, China PR, Kyrgyz Republic

Defending champions Saudi Arabia and China PR will be familiar foes, having faced off in Group A of the Qualifiers which ended 1-0 in favour of the West Asians.

The presence of Japan, who have surprisingly only won the title once - in 2016 - adds more spice to the group.

Saudi Arabia advanced after topping Group A, with China PR through as one of the best five runners-up while Japan were peerless in Group C with four wins.

Saudi Arabia will be chasing a fourth title while China PR have only lifted the trophy once, in 1985.

Kyrgyz Republic will be making only their second appearance in the Finals but the Central Asian side will relish the chance of not only locking horns against their more illustrious opponents but also sealing a place in the knockout stage.
