Finn Russell is hoping Scotland can end their Twickenham losing streak against England
The Kiwi will take charge of his penultimate game as Scotland coach before heading off to Montpellier hell bent on ending England's 34-year home domination of the Calcutta Cup.
And playmaker Russell confirmed his team's desperation to put a rare smile on the face of 'Stern Vern' on Saturday by delivering it.
"Vern has been great for the last three years. He's known he has been leaving but he has still given this competition his all. He wants to be as successful as possible," said Russell. "It is his second-last game and it's a big one so we'll definitely be going down there and trying to get the win for him and for us.
"We know how tough it is going to be. We've not won there for a while but we're playing pretty well just now."
Vern Cotter will be leaving for Montpellier after the Six Nations with Scotland
Both sides will reveal their hand today with England set to make four changes from the side which beat Italy including the return of Billy Vunipola at No 8.
Vunipola had initially been ruled out of the Six Nations by a knee injury but he has impressed sufficiently in training to be thrown into the starting line-up after just 72 minutes of rugby in three months.
"It's surprising how well he's moving and in training he looks up to speed as well. It's good to see him back in and doing what he loves," said elder brother Mako, who has also returned ahead of schedule from a knee injury during this championship.
"I think he was jealous that I was running before him and out on the field before him. That's what spurred him on to get back.

"If I go down he'll come over and say 'get back up', if he goes down I say the same to him. I don't want to say we're the toughest men ever, it's more that we don't want to show a weakness to the other brother."
Wales No 8 Ross Moriarty has held off the challenge of Taulupe Faletau for a starting place against Ireland in Cardiff tomorrow night with Wales unchanged from the defeat against Scotland.
"There's an opportunity to go out at home in front of our own supporters and deliver a performance which the players are proud of and for the supporters to support that. It will be a huge game on Friday night and we expect a reaction," said Wales caretaker coach Rob Howley.
Ireland make just one alteration on the bench with Tommy Bowe recalled for the injured Andrew Trimble.
Meanwhile, Exeter scrum-half Niki Matawalu has appeared in court charged with sexual assault. The 27-year-old Fijian international, who pleaded not guilty to the offence which is alleged to have taken place in Exeter on December 3, will stand trial on August 10.
