The German centre-back imposed himself by scoring two headers in the rout, earning himself an 8.8 Flashscore player rating – the joint-highest of the week with Brighton's Maxim De Cuyper.
However, Thiaw takes the mantle for his impact in Newcastle's outing, which got off to the perfect start inside one minute at the Hill Dickinson Stadium.
Thiaw rose the highest to nod in the opener after just 55 seconds, which is the Premier League's fastest goal of the season so far.
Winning seven duels and making five clearances too, Thiaw scored his second in similar fashion before the hour mark to further extend the Magpies' lead.
A quick turnaround in the division will see Newcastle next play Tottenham at St James' Park on Tuesday night.
