Australia coach Graham Arnold described Mathew Leckie's return from injury as "like signing a new player" as he confirmed the Hertha Berlin winger's place among his substitutes for the last-16 clash with Uzbekistan at the Asian Cup.

Leckie is ready for his first involvement at this year's tournament following his recovery from a hamstring problem that ruled him out of all three of Australia's Group B matches.

Arnold's side finished second in the group after defeat to Jordan preceded victories over Palestine and Syria, and Leckie is joined in the squad for the clash with Uzbekistan by fit-again defender Josh Risdon and by Trent Sainsbury, who was suspended for the Socceroos' final group game.

Arnold paid tribute to the Australia medical team for ensuring Leckie's availability, and said his side are ready to follow up their dramatic 3-2 win over Syria with another victory.

"The wonderful thing is Mathew Leckie is back and he will be on the bench," said Arnold.

"It's like signing a new player halfway through a tournament. We planned when he got injured at Hertha Berlin that we needed to look at how the injury would come along.

"We were patient with that and our medical staff have done a great job getting him ready. And that, with his positive attitude and how he is in camp and in around the boys, has given the boys a lift already.

"Josh Risdon is back again, so he will be back, and Trent Sainsbury is back from suspension. Andrew Nabbout is the only one out at this stage so we're getting stronger and stronger as the tournament goes.

"We're into the last 16, so it's a step up in the competition and a step up in the tournament and I expect our team to step up another level as well.

"But we've analysed them and we expect to expose their weaknesses. They've had a three-day turnaround and we've had five so we're mentally fresh and feel great and are ready to go for this game."

Uzbekistan made sure of their progress to the knockout stages with victories over Oman and Turkmenistan in their first two Group F matches, before taking the lead against Japan only to lose 2-1 on Wednesday.

Head coach Hector Cuper promised some changes to his team but said there would be no diversion from the approach that has taken them beyond the group stage for the fifth consecutive tournament.

"We know the importance of tomorrow's game," said the former Valencia and Inter coach.

"It's the knockout stage, so we have no room to make errors. We will come to the pitch to win, but at the same time we realise Australia are a tough rival and one of the best teams in Asia.

"During the last three days we have tried to improve on all of our mistakes and we have tried to analyse the Australia side. Based on their advantages, we will make some changes but it doesn't mean we're going to change the system or style of our game.

"We will come to the pitch and the players will do their best to get the necessary result."

PLAYERS TO WATCH

Australia - Tom Rogic

In the post-Tim Cahill era, Celtic's Rogic is the man Australia look to for match-winning moments and big-game performances. He delivered both against Syria, showing class and composure as he picked his spot before coolly driving home the Socceroos' stoppage-time winner, and he will be full of confidence against Uzbekistan.

Uzbekistan - Eldor Shomurodov

Arnold will know all about Uzbekistan's star striker Shomurodov - one of the players of the tournament so far. The 23-year-old Rostov forward scored in all three of his country's group games, including a brace in their 4-0 win over Turkmenistan, and he thrives on the vision of Javokhir Sidikov and the craft of Jaloliddin Masharipov in midfield.

KEY OPTA FACTS

- Australia have reached the Asian Cup knockout stages in each of their four participants in the tournament, winning five of their last six such games (L1).
- Uzbekistan have only ever won one of their six Asian Cup knockout games (D1 L4), a 2-1 victory against Jordan in the 2011 quarter-final.
- Shomurodov scored in all three of Uzbekistan's group-stage matches at the 2019 Asian Cup (four goals) – the only other player to do this was Qatar's Almoez Ali.
