New Yokohama F. Marinos manager Ange Postecoglou has "no regrets" about quitting Australia's national team just months before the World Cup and is looking forward to testing his mettle in the J. League instead.

"People in Australia have struggled with it, but it's just the way I am," Postecoglou told The Japan Times of his shock decision to resign as Socceroos manager in November, one week after leading them to a place at Russia 2018. "It's just me as a person and my journey in life. When I feel the time's right, I feel the time's right.

"No regrets. I had a fantastic four years. It was obviously a tough decision but it was something that I'd thought about for a very long time. When the World Cup is on there will be a little part of me that has a little bit of angst towards not being there, but I'm certainly hoping that they will do well there and I've got a real belief that they can."
