Scotland have produced a blistering display of attacking rugby to hand Eddie Jones just his second defeat as England head coach and end the visitors' Grand Slam aspirations with a 25-13 Six Nations victory at Murrayfield.
It was only Jones' second defeat in 26 Tests in charge of the national team, with the other coming against Ireland in the final match of last year's Six Nations.
But the hosts eventually held out for an emotional victory to outline their credentials as serious title challengers this year, and Russell admits they can still improve.
"Whenever England play anyone they want to beat them, the opposition want to beat them, Scotland, Wales, France, Ireland, they all want to beat England so every game's big, every game's fought and won". "That's disappointing", Jones said.
"Going over there, whatever we did here, we'll have to up that performance". "I take full responsibility and I have to work out what I did wrong and work out how to fix it".
But instead Russell took the bolder course, his well-weighted grubber kick causing panic in England's defence and bounced kindly for outside centre Jones, who dived on the loose ball for a try under the posts which Laidlaw duly converted to make it 10-3.
Scotland went back on the offensive and their cause was aided when Sam Underhill was sin-binned for a no arms tackle, allowing Russell to land a penalty that opened a 12-point lead with 14 minutes remaining. It's 138 years of rugby history.
"We knew what we were going to get but we didn't meet the challenge today for some reason".
England had travelled to Edinburgh well aware of the tricks that would be thrown at them as kick-off approached.
World Cup-winning captain and ex-head coach Johnson has urged England to put the game to bed to avoid suffering the same fate as Les Bleus.
At least not for the first 40 minutes. We'll learn a lot from this. "Unfortunately, the lesson isn't sometimes nice to take but it is a great lesson for us". Second half I was very proud of the effort of the boys. "I didn't prepare the team as well as I should have and that's my fault".
Meanwhile England will travel to Paris to face a resurgent French side who will look to build on last night's victory over Italy.
"It's a feeling I've never had [beating England]", he said, having been named man of the match.
The worry for Scotland, who came from behind to beat France, is that recovering from a sluggish start against England last year, is something else entirely particularly if Jones's men can, as they did in a dominating 61-21 Calcutta Cup win at Twickenham last year, cut through an often fragile midfield defence.
