Schwarzer, 38, has been in career-best form for the past few seasons with club Fulham and the Socceroos and insists retirement isn't on his mind.

“I’m still very much in the plans of my coach Holger Osieck and I believe that I have a lot more to give,” Schwarzer told fulhamfc.co.uk.

“I’ve been extremely fortunate to have played at two World Cups and who’s to say that I can’t make it to a third?”

Schwarzer pointed to the example of Manchester United's 40-year-old goalkeeper Edwin van der Sar as prove there's no age-limit for glovemen.

“He’s widely considered as one of the best in the business,” Schwarzer said. “He’s enjoyed a fantastic career and I know he did well for this club too. It will be a shame when he calls it a day.

“I’ve got a few years on Edwin though, but he’s certainly someone that I look at and think that if he can play at the top for as long as he has then I can do the same.

“Alongside Brad Friedel he’s shown what can be achieved and I don’t think there’s a marker for how long a goalkeeper can go on for now.”

“There’s been a lot of advancements in the game to allow that to happen. I made a conscious decision to change my regime not too long ago, and with the help that I get from the Sports Science Department, the nutritionist and the Strength and Conditioning team it seems to be working.

“I’m still training with the same intensity, but I’m now doing up to four sessions a week in the gym and have changed my diet a fair bit too – I feel a lot better for it though.

“It’s not rocket science either, it’s really all about discipline. Fortunately I have that, probably as a result of my German heritage!”

Schwarzer continued it's also important he continues to enjoy playing the game.

“For me that’s one of the most important factors,” Schwarzer said. “We’ve talked about maintaining your time at the top and keeping yourself fit and healthy. But equally, you have to have that love for the game – which is another reason to keep playing.

“Too many people these days just don’t have that. My son Julian plays for the Academy’s Under-11s and there are boys of that age running around without a smile on their face. That’s a very sad thing.

“Sometimes this game can be too serious. Of course, we all want to win and be successful, but I think the reason why we all started playing can be lost at times.

“The magnitude of games is massive, but you have to have that element of enjoyment – people undervalue how significant that can be. That also breeds success.”

Schwarzer added he'd love to extend his current stint with Fulham.

“I feel as good as I ever have done, I work hard and I’m performing – which for me is the ultimate consideration,” he said.

“As long as I am playing well week-in-week-out and the manager is playing me then I’ll be around for a while to come.

“I have signed a contract that keeps me at Fulham until the end of next season, and potentially there could be another year after that too.”

And Schwarzer concluded he was delighted to become Australia's most capped player when he appeared in the green-and-gold for the 88th time at the Asian Cup final.

“It’s something that I will look back on in years to come and probably pinch myself,” he said.

“Winning my 88th cap in the final made for a tremendous occasion, but losing the game to Japan kind of took the gloss off a little.

“It was an unforgettable moment and hopefully I can extend that record a bit further.”
