Eight seasons ago, Ireland's scrum collapsed under the weight of a powerful English scrum and Declan Kidney's side were beaten out the gate at Twickenham.
Last autumn's World Cup final brought back memories of that day when Tom Court, a loosehead who was the sole replacement prop on the Irish bench, was brought on for the injured tighthead Mike Ross early and was marched backwards at every turn.
England had no such excuse as they ceded momentum to a rampant Springbok eight, with Tendai 'Beast' Mtawarira dominating Dan Cole who'd replaced the sparked Kyle Sinckler after just one minute.
It was at once a throwback and a reminder of the relevance of the importance of the scrum in the modern game.
In the decade since Ireland's emasculation at the home of English rugby, they have turned their scrum from a potential weakness to a source of strength.
So, Tuesday's bizarre claims from Wales about Tadhg Furlong's illegality at scrum-time rang hollow.
Ten days after Ireland comfortably beat the Welsh in Dublin they came out swinging, with forwards coach Jonathan Humphreys accusing the Leinster prop of "hammering across the scrum" during the game.
"When you're dealing with tightheads like Furlong who is going to come right across the scrum from left to right, it creates problems and instability," he said.
"We have to make sure we're diligent in that area and there is a little inconsistency."
The 27-year-old Furlong will win his 47th cap at Twickenham and this is the first time during that period where he’s come in for criticism about his technique.
He took over from Ross as the guardian of the No 3 jersey in 2016 and has a been a world-leading force on the tighthead side of the scrum ever since.
Under Joe Schmidt and his national scrum coach Greg Feek, the prop stocks have boomed and Ireland have been renowned as a positive scrummaging team who prefer to play off the set-piece rather than milk penalties.
They are undergoing some changes under Feek's replacement John Fogarty and, unusually, fell foul of referee Mathieu Raynal in the opening game against Scotland and they conceded a scrum penalty in the opening minutes of the win over Wales.
From then on, however, their scrum went well and they can rely on it as a weapon as they consider their trip to London this weekend.
England have recovered from their scrum disaster against South Africa by going through 160 minutes against France and Scotland without conceding a scrum penalty.
Eddie Jones has moved Cole on, with Sinckler his starting tighthead, but he will be without his first-choice loosehead prop Mako Vunipola for Saturday’s match.
The Saracens star has travelled to Tonga to attend a family matter, denying England their man of the match from last year’s sensational Six Nations opener in Dublin.
Jones can call on the experienced Joe Marler, but also has the option of picking Ellis Genge who came off the bench to destructive effect in both of their games so far.
Marler is the more experienced operator, but the outspoken Leicester prop is a sensational athlete who plays with a chip on his shoulder that gives him a real edge in his play.
They struggled in Yokohama, but no-one in the Six Nations can match South Africa’s power and Ireland won't go to Twickenham believing they can bully the English scrum.
But, with Lions Cian Healy and Tadhg Furlong starting either side of Rob Herring, and the dynamic triumvirate of Dave KIlcoyne, Ronan Kelleher and Andrew Porter ready to come off the bench and impact the game, they won’t be found wanting in that area.
Less than a decade on from their disastrous day at Twickenham, they no longer make the short trip with worries around their set-piece.
Humphreys' comments will draw the focus and Jones may look to put more pressure on this week.
No doubt referee Jaco Peyper will be made aware of the Welsh perception, so they'll need to be squeaky clean.
Still, eight years on from their 30-9 loss at the same venue, Ireland will be confident they can ride out any storm and deal with whatever the English pack throw at them.
