Harlequins Rugby Director Conor O'Shea had warned his team to expect a tough time against a Newcastle team fighting for Aviva Premiership survival when they hosted the Falcons at the Stoop on Sunday.
And the table-toppers were not disappointed - despite dominating their opponents to win 39-8.
"That was incredibly physical. They have a massive pack and two kicking experts in Gopperth and Manning," said O'Shea.
"We have some walking wounded in the dressing room, but they'll get over it. The win is fantastic because Nick Easter spoke to the players before the game and said they'd really have to turn up or get beaten. They turned up.
"He played fantastically well in the first half before tweaking an ankle which is why he went off.
"Jordan Turner-Hall is pretty beaten up after making the mistake of running into Taiasina Tu'ifua, and there's only ever one winner in that situation. But he's a better player now than two years ago and getting better with experience."
Quins are now nine points clear of Saracens, but O'Shea will not allow anyone at the club to get big-headed.
"There was an unfair degree of expectation around the place beforehand which was unfair because you simply do not get anything resembling an easy game in this Premiership." he added.
"I've lost badly to Newcastle in the past. One of the all-time low points in my career was losing to them here in the LV= Cup semifinal last season. It was awful. You don't forget those days.
"You don't go out believing that you'll run riot because of our position in the table or their league placing. It does not work that way and you dare not be that arrogant or you come up short."
Newcastle head coach Alan Tait bemoaned his side's poor finishing for the eventual margin on the scoreboard.
"We have some guys a bit busted up in there, but they are the top side in the division and we pushed them at times only to let ourselves down with poor finishing," he said.
"We say it every week in the dressing room but then we go out and give sloppy offloads, throwing the ball away. One minute we are attacking, the next they are away off our ball and scoring tries.
"I'll make some of them watch the video of the game during the week because we cannot keep doing this."
But Tait refuses to consider relegation and insists his squad have the quality to avoid the drop for another season.
"There's a long way to go still and a lot of rugby to be played," he added.
"This squad is good enough to stay up, providing we start taking our chances. But you have to get you heads up. We can compete physically but we need to finish with more sharpness."
Harlequins were the better side, however, their six-try haul creating a record start dating back to the season's start on September 3.
Seb Stegmann scored two tries, Mike Brown, Danny Care, Luke Wallace and James Johnston one each while Nick Evans kicked seven points, Rory Clegg two. Jeremy Manning scored Newcastle's try, while Gopperth kicked a penalty.
