Two weeks ago, Scotland came from behind to grab a 6-6 draw in Colleferro – their first championship points on the road since 2006 – but missed a host of late chances to win the match.

And Parker, who has picked an unchanged lineup for the England match, believes Saturday’s result will be a mark of his side's progression against top class opposition following last year’s 72-3 mauling by England.

He said: "Although disappointed not to win against Italy there were still a lot of positives to take out of the game, none more so than gaining our first point on the road since 2006.

"The next challenge couldn't be greater though, as the world's best side, England, arrive looking to maintain their 100 per cent record in the championship.

“They have set the benchmark for all the teams to aspire to and can be ruthless, as last year's result demonstrated.

“We know the challenge that England will pose and this game will allow us to further measure the improvements we have made this season."
