Eight different goalscorers for Eddie Howe's Newcastle United helped them inflict the heaviest ever home league defeat on Sheffield United.
It was 3-0 at half-time, with five goals in the second half, as the Magpies proved there was no Champions League hangover despite their trip to Milan in the week.
Harvey Barnes was taken off injured early in the clash, but his replacement Anthony Gordon put in a man-of-the-match performance at Bramall Lane.
The Blades looked beleaguered from the moment Sean Longstaff broke the deadlock (21), with defenders Dan Burn (31) and Sven Botman (35) extending the visitors' lead before the break.
Heckingbottom was in need of a rousing response after the restart, but what he got was Sheffield United's worst-ever home defeat as Callum Wilson added a fourth (56) from a third Kieran Trippier assist.
Anthony Gordon, who was electric throughout, curled home goal number five four minutes later as the home fans headed for the exits in their droves.
Those who remained witnessed Miguel Almiron race through to add a sixth (68) and Bruno Guimaraes made it 7-0 before Alexander Isak pounced on a Tom Davies mistake to put the seal on Newcastle's biggest-ever Premier League away win (87).
Sheff Utd, still seeking their first Premier League win since returning to the top flight, sink to the bottom of the division with a goal difference of -12, while Newcastle rise to eighth following back-to-back wins.
