Socceroos captain Mat Ryan struggles to find the words to capture the feeling.

His teammate Martin Boyle is a bit more succinct. He regards it the best feeling of his life.

And with World Cup qualification on home soil on the line for the Socceroos in Perth on Thursday night, two of Australia’s experienced campaigners are desperate to taste that feeling again.

Preparations are well underway for the Socceroos ahead of their blockbuster against Japan at Optus Stadium, with an Australian win potentially enough to seal qualification for a sixth successive World Cup.

Ryan played in qualification play-offs to help the Socceroos reach both the 2018 and 2022 tournaments, with Boyle taking part in the penalty shoot-out win over Peru in the latter.

For goalkeeper Ryan, it is still hard to fully explain what being part of those two successful campaigns meant.

“It’s a difficult one to find words to describe the ecstasy of it. As a footballer, there’s no more meaningful moment than a World Cup qualification like that,” he said.

“There’s a few us boys in here that have tasted that in the past. It feeds your hunger and motivation to want more of it.

“We do our best, for the guys that haven’t been to a World Cup before, to story-tell and share experiences, to try and further motivate them and educate them on what it takes to get there.”

Boyle missed out on the 2022 World Cup due to a torn ACL, but travelled with the side to Qatar regardless as the team’s unofficial ‘chief vibes manager’.

While injury may have dampened his experience of the Socceroos’ run to the round of 16, Boyle said helping them earn qualification was a career highlight.

“To this day, it’s probably the greatest achievement I’ve had my career, to qualify for that World Cup,” he said.

“There’s no better feeling, just the adrenaline, the buzz, it’s the pinnacle of people’s careers.

“Being selected for the World Cup could maybe tip that, but qualifying and to know you’ve done it, to help your nation qualify for a World Cup, it’s a special feeling.

“We’ll be drilling that into the lads. We have good experience.”

With Japan already qualified for the 2026 tournament, to be held in North America, they have brought an inexperienced squad minus several stars.

But while Ryan said they were not taking the Blue Samurai lightly, it was his firm belief the Socceroos were Asia’s strongest team.

“In my eyes, we’re the best in Asia. If you don’t believe you’re the best, then you’re failing at the first hurdle,” he said.

“You’ve got to go out there and believe that you can overcome whatever challenge is in front of you and obviously there’s a fine line without being arrogant and being complacent or anything like that.”

The pressure will be on Australia on Thursday, but Boyle could not be more excited.

“These are the games you want to play in, they’re massive games.

“These are the games you can be a hero in. Certainly everyone will have an eye on doing that, but most importantly is to qualify for the nation — we know how difficult it’ll be.”
