Last-placed Parramatta gave caretaker coach Brad Arthur a dream NRL debut and left Brisbane's premiership claims in a mess at Suncorp Stadium on Monday night.
The rejuvenated Eels pulled off their second stunning upset in as many weeks backing up their win over Melbourne with a surprisingly easy 42-22 win over the Broncos.
Arthur, who took over from head coach Stephen Kearney this week, delivered on a pre-game promise to take the shackles off expensive halfback recruit Chris Sandow who took the first steps to convincing Parramatta fans he will be worth his high price tag.
The little No.7 grabbed two tries - the second racing 50 metres and standing up speedy Brisbane back Gerard Beale before diving across the try line.
Parramatta piled on five converted tries in the opening 40 minutes against the defensively woeful Broncos to lead 30-6.
