Ange Postecoglou says he doesn't "have to prove anything to anyone" as he starts his reign as Nottingham Forest's new boss.
Postecoglou was appointed on Tuesday, with the club sacking Nuno Espirito Santo late on Monday after 21 months in charge at the City Ground.
The Australian returns to management three months after he was sacked by Tottenham following a dismal Premier League season, in which they finished 17th.
However, Postecoglou ended Spurs' 17-year trophy drought by leading them to the Europa League title in May.
The 60-year-old was initially praised for the attacking style he implemented at Spurs, but he was forced to defend himself from criticism for sticking to his high-intensity principles as Spurs lost 22 of their 38 league matches last season.
