Tottenham confirmed the appointment of the 57-year-old Australian as their new manager earlier today.
Postecoglou left Celtic after two hugely successful seasons where he won the domestic treble as well to join Tottenham on a four-year contract.
He is the first Australian to get a chance to manage in the Premier League and Johnson claimed that it is a milestone moment for both Postecoglou and Australia as a sporting nation.
Johnson admitted that Football Australia are delighted to see a fellow Australian get a chance to prove his credentials at a major Premier League club.
He believes Postecoglou getting the Tottenham job is a sign of his quality and determination to break barriers and make a name for himself in one of the top leagues in Europe.
The Football Australia CEO also believes that Postecoglou’s rise to the helm of Tottenham is also a sign of the nation’s growing importance in the world of football and a matter of pride for Australia.
Johnson said in a statement on Football Australia’s official website: “On behalf of Football Australia, we would like to congratulate Ange on his appointment to English Premier League club, Tottenham Hotspur Football Club.
“This appointment is a personal triumph for Ange and his family, and we are absolutely delighted for them.
“Ange personifies the Australian football story: a proud Greek-Australian who immigrated to Australia at a young age and found his place in a new Australia through football.
“After making a name for himself domestically, from his playing days at South Melbourne Football Club to his success as Socceroos’ head coach leading the team to Asian Cup glory in 2015 on home soil, Ange has gone on to test himself successfully in the global football arena against the world’s best.
“This new chapter at Spurs for Ange is a testament to his enduring determination, skill, and vision as a leader.
“It is also a moment of great pride for Australian football and highlights this current golden age as we see more of our coaches making an impact on football around the globe and a steady presence of players across European leagues, particularly in Great Britain.
“Together with our co-hosting of the FIFA Women’s World Cup commencing next month, this is a clear indication that our country has emerged as a new power in global football and underlines the compelling legacy we are building for Australian football.”
Postecoglou has a big job on his hands in reinvigorating a Tottenham side who failed to qualify for European football in the just-concluded Premier League season.
