Warner had fallen out with several teammates after being identified as the architect of the ball-tampering plot which brought Australian cricket to its knees.
Rating the 2004 series triumph against India on their home turf as one of the most memorable moments of his 105-Test playing career, Langer said that the new-look Australian team could fix their tarnish public image by succeeding the Virat Kohli-led side in early 2021.
"To me, respect's worth more than all the gold in the world".
"We've got a World Cup, a T20 World Cup, a couple of Ashes (in 2019 and 2021-22) - I get nervous when I start thinking about it", Langer said. "We will judge ourselves on whether we're a great cricket team, if we beat India in India", the former opener declared.
Langer's first assignment is next month's one-day worldwide series against world number one England.
Langer's tenure includes next year's World Cup, two Ashes series and a World T20 on home soil but he has identified victory on Australia's next Test tour of India as the number one long-term goal.
"What I know is we should be very proud of our history of Australian cricketers", he said.
"While Darren Lehmann was not due to complete his term until next year, we have had a succession plan in place for this role for some time", said Sutherland.
He was appointed as the batting coach for the national team from 2009-12 before taking over as head coach in Western Australia in 2012. There is still 11 months before he has the services of Steven Smith and David Warner.
"That said, we can also modify our behaviours a bit so it's not angry, not over-aggressive, but we're certainly aggressive in the mindset we play with the bat and the ball".
When local media asked Langer if he would leave the door open to Smith, Warner and Bancroft returning, he said "of course, they will be welcomed back". The new coach inherits a team that sits third on the International Cricket Council Test rankings, fifth in one-day internationals, but one that has lost much of the support it had from the Australian public.
Like his predecessor Lehmann, Langer carved out a career in some of Australia's most successful and uncompromising teams in the 1990s and early 2000s, led by captains that championed "hard, aggressive cricket" and never apologised for the use of targeted sledging to throw opponents off their games.
