The disappointment of defeat to Wales has lingered in the Scotland camp but captain Alastair Kellock is determined to right the wrongs in Sunday's RBS 6 Nations clash with Ireland.
Scotland suffered a 24-6 loss in an error-strewn display as Wales ended an eight-Test winless run at Murrayfield.
The Glasgow Warriors second row said: "It's important we move on, it's important we focus on Ireland. What we've got to have is a performance that deserves a victory."
He added: "We showed against Wales when we're off par what a team can do to us.
"If we play well we have the ability to beat anybody, if we don't then we won't.
"We might need a bit of luck, we might need the bounce of the ball here and there, but we want to be right in the game."
Three of the seven changes to the side were enforced, with Hugo Southwell (cheek) and Joe Ansbro (concussion) injured and Euan Murray unavailable due to his religious beliefs preventing him from playing on Sundays.
Tighthead prop Moray Low, lock Richie Gray, number eight Johnnie Beattie, scrum-half Mike Blair, fly-half Ruaridh Jackson, full-back Chris Paterson and Lamont, who will line up at inside centre, have been called into the starting XV.
Kellock is excited to see Beattie return to the side, his Glasgow team-mate having not played for Scotland since the 2-0 Test series win in Argentina following shoulder surgery.
Kellock added: "Johnnie's a terrific player. He can do things in a game that possibly nobody else can. We will need to get him involved. He'll need to work hard to get his hands on the ball and if he does that I'm sure he'll be a big factor in Sunday's game."
