Mathew Leckie is backing himself to cause Saudi Arabia all sorts of problems as the Socceroos aim to keep their 2018 World Cup qualification hopes alive.

The Hertha Berlin winger has scored from corners in the two previous qualifiers against Iraq and UAE.

And Australia are desperate to beat table-topping Saudi Arabia in Adelaide on Thursday night to keep themselves on track for a place in the finals in Russia next year. Currently Saudi Arabia are equal top with Japan on 16 points, with Australia three points behind in third.

With the top two teams from their group automatically qualifying, a win against their Middle Eastern opponents will put the Aussies in the box seat in their quest to qualify.

And Leckie knows he can pose a big threat following his goals against Iraq and UAE.

“I know I can be dangerous from set pieces, I’m not too big but I get up pretty high," he said. “I was very happy to score and on a personal note to score a couple in a row it builds the confidence."

With the Socceroos having home advantage, former Adelaide United star Leckie believes Australia can secure a win in front of their passionate fans.

“Playing at home is huge. All our home games are huge,” he said. “I’m very confident that we will dominant the game in Adelaide. The main thing is just getting those three points.

"I’m more than confident that we will do that because we are very, very difficult to stop at home and we have shown that in the last couple of years.”

Having the experience of playing the much publicised 3-4-3 in two competitive fixtures has made Leckie confident that the Socceroos will be fully prepared for Thursday night’s crucial contest.

“Everyone knows now that we can adapt to the new formation,” he said. “We knew that we could be very dangerous if we made it work. In patches against Iraq we did well and after the game we knew there were things we needed to work on.

“The media obviously blew it off straight away and said we weren’t confident playing with it, but we knew that if we stuck by it we’d do well and against the UAE it was a good performance. “

 “We now have a very solid last few games at home and one away, so we are confident that we will pick up the points we need to get to Russia.”
