The Australian arrived from Celtic last summer with a reputation for playing an ultra-attacking style of football, which had helped him claim five trophies in two years in Scotland.
He inherited a Spurs squad desperately needing a reset after missing out on European football while shuffling through Antonio Conte, Cristian Stellini and Ryan Mason in the dugout.
