Far from being overawed by the occasion,Mooy displayed guile and composure ensuring that Huddersfield's first top-flight clash in nearly 45 years was unforgettable.
A brace to Steve Mounie and some stunning build up work from the Socceroo did the damage with Mooy instrumental in getting the Terriers first ever Premier League goal.
A dangerous corner by the 26-year-old caused split second havoc in the box as it was flicked on at the near post before being bundled over the line by Joel Ward for an own goal on 23 minutes.

Three minutes later Town's Player of the Season last term helped Mounie to his first of two with a perfect cross to the striker who headed it home.

Mounie completed the rout on 78 minutes leading to raucous celebrations from the away support.
