Ange Postecoglou says he will not be happy unless he sets Spurs up for 'sustained success' by the time he leaves.
Spurs have not won silverware since 2008 when they lifted the League Cup under Juande Ramos but came close when they finished runners-up in the Premier League and the Champions League under Mauricio Pochettino.
The club has been stung by criticism from former captain Hugo Lloris in his new book, who suggested the club were happy to finish second during his spell there.
But Postecoglou says his job is about more than just ending that long trophy drought.
