Wales head to Scotland in search of their first victory over a major rugby-playing nation since Gareth Jenkins took charge last summer.
And after watching his side fail to score a try in their 19-9 defeat to Ireland last weekend, the head coach admits he is beginning to feel the pressure.
'Put yourself in my position. Since I've been in the job, we've only beaten two teams (Canada and the Pacific Islands) and both of them were outside the top 10 ranked sides,' said Jenkins.
'It's right to say the pressure is on because it's the first time we have played a top-10 team below us in the rankings.'
The last time Wales travelled to Edinburgh they produced a stunning display of attacking rugby and a record 46-22 victory left them one win away from the Grand Slam.
But as Wales head north in the hope of keeping their 2007 title campaign alive, Jenkins insisted: 'Those memories are in the past and, like the Scottish anthem says, in the past they must remain'.
Jenkins has made four changes for the game, calling Ospreys props Adam and Duncan Jones into the front row and replacing lock Ian Gough with Rob Sidoli.
Mark Jones returns on the wing after recovering from an ankle injury and will bring the finishing qualities Wales so badly missed last weekend.
'It is a case of re-energising the team after our short six-day turnaround,' said Jenkins.
Scotland boss Frank Hadden has rejigged his resources after last weekend's 42-20 defeat to England at Twickenham.
Phil Godman starts at fly-half and Rob Dewey comes in at inside centre with Scott Murray, who was sent off against Wales last year, reinstalled into the second row.
It is a more attacking line-up and captain Chris Paterson is confident Scotland can repeat their memorable home performances last season, when they accounted for both France and England.
'Confidence is high, we're at home, and it is going to be a sell-out - so that will inspire us to get the victory we are looking for,' said Paterson.
'My biggest worry would be if the commitment and attitude wasn't there last week, but it was and it will be there again this weekend.
'And with the work we have put in decision-making wise it will be an entirely different game this weekend.
'I'm sure we'll get the win we are looking for.'
