Ange Postecoglou's status as the greatest football coach ever produced by Australia has arguably been cemented after he led Yokohama F. Marinos to the J.League crown.
Needing to avoid a heavy defeat to secure their first Japanese title in 15 years, Yokohama wrapped up the championship in style with a 3-0 win over nearest rivals FC Tokyo.
The victory, secured despite going down to 10 men in the second half, means Yokohama finished six points clear at the top of the J1 league.
"We're champions!" the ex-Socceroos boss said after the victory.
"I'm very proud of the players, very proud of the staff.
"We've got fantastic supporters and I'm very happy for them."
Postecoglou's latest success adds to a managerial honour roll that already included Australia's 2015 Asian Cup win, two A-League championships with Brisbane Roar and two NSL titles with South Melbourne.
The 54-year-old also possesses the longest undefeated streak in any Australian domestic football code of 36 matches and successfully qualified the Socceroos for the 2018 World Cup in Russia.
Postecoglou was appointed Yokohama's head coach in December 2017, a month after his shock resignation from the Socceroos role despite the successful World Cup qualification campaign.
He took the club to 12th position in the J-League in his first season in charge and his transformation of the club into champions with a typically attacking and expansive style has sparked rumours he could soon find himself in one of Europe's top leagues.
He's also been touted as a possible candidate to coach the Japanese national team in the future.
Despite those rumours, Postecoglou distanced himself from any move away from Yokohama.
"I'm definitely going to be around next year for sure," he said.
"There's still stuff that I want to do here. I still think we can be better."
