Russell Martin says he is "not going to make any promises" after becoming Rangers' new head coach but insists they must "win early and win while developing".
The former Scotland defender, 39, has signed a three-year contract to become one of the key early appointments at start of a fresh era at Ibrox.
A US-based consortium, led by Andrew Cavenagh and including the investment arm of the San Francisco 49ers, completed a takeover of the club last week.
And former Southampton and Swansea City boss Martin - who had a short stint as a player at Ibrox - was the "standout choice" to lead the team after a prolonged recruitment process.
"Winning is how you convince people - players, staff and supporters," he said at his unveiling at Ibrox on Thursday.
"We had to do that at Southampton - we had to win in amongst a lot of change."
