If there is a fly which resides on a wall in the away dressing room at Franklin’s Gardens, it will not be enjoying a quiet life.
So many teams have entered those four walls with a positive result in mind, yet left with the words of their management ringing in their ears.
On Saturday, it was Sale’s turn.
Sharks to the slaughter, they added their name to a list of victims who have not only been beaten, but systematically dismantled by Saints.
And so angry was their boss, Steve Diamond, that he opted not to conduct a post-match media conference.
Instead, he sent the Sale press officer to convey the message that there were no positives to take.
That his side had sparked their own downfall.
And you can imagine that those sentiments included more than a few expletives when they were uttered directly to the players.
But if there is to be any solace for Sale, it is that they are not the first side, and will not be the last, who have been blown away by the champions.
If you’re a fan of statistics, how about this one: Saints have scored a total of 201 points in their previous four regular-season Premiership home games combined.
And the teams that make up that quartet - Wasps, Gloucester, Bath and Sale - are far from relegation-fodder.
So while Sale are beating themselves up, the other side of the coin sees Saints deservedly head the Premiership table.
They did not slay the Sharks purely because of the visitors’ errors.
They drowned the men in white with power, precision and pace, especially from the Pisi brothers.
Ken dazzled, slaloming his way through the Sale rearguard like a star skier before setting up sibling George for Saints’ third with a superb gather.
Kahn Fotuali’i also scored as the Polynesian players took centre stage, while Samu Manoa, American by birth but with strong Tongan ties, iced the cake with a hat-trick.
And Saints could even afford to pick their time to bring on the likes of Dylan Hartley and George North, whose arrival gave yet another glowing example of the squad’s depth.
All of that strength will be needed when the European assault gets underway next weekend, but for now another huge home victory can be savoured.
As for Sale, their defeat is another reminder of how tough it will be to beat Saints on home turf this season.
Franklin’s Gardens is fast acquiring the kind of fearsome status Welford Road has held for so many years.
Teams may not say it publicly - Sale stated their willingness to be adventurous prior to Saturday’s tussle - but many must surely fear to tread on Piggy Powell’s patch now.
And that visiting dressing room is just as unwelcoming.

KEN PISI - CHRON STAR MAN

Came in at late notice for James Craig, who was ill, and proceeded to steer Saints around the park with a typically assured performance... 7
An emotional day as he led Saints out alongside Georgia Ghaut, sister of Luis, and he put plenty of passion into his performance as always... 7
Was withdrawn at half-time but had made an impact until then and continues to impress in a Saints shirt... 7
It’s unusual to score a hat-trick and not win the man of the match award, but Manoa won’t care as he grabbed three opportunistic tries and put in a fine performance... 9

CALUM CLARK (for Lawes 57)
Always adds energy to proceedings and helped his side stay strong in defence as Sale sought consolation scores... 6

GEORGE NORTH (for K Pisi 57)
Did his best to add to the glut of tries, but was halted by Sale as they tried to avoid further embarrassment... 6
