Former lock Doddie Weir says it is time for Scotland to show their talk is not cheap and deliver a match-winning performance against Wales.
After the opening defeat to England, Scotland's players have spoken about the need "to prove they are the team they think they are".
"Not to be too rude about it but talk is sometimes cheap," said Weir.
"We'd like to see a performance because I thought things in the Six Nations were going to go well."
Scotland are currently on their worst ever losing run since the Five Nations became Six in 2000 - eight games stretching back to a win over Italy in February 2014 - and head coach Vern Cotter is yet to experience victory in the tournament.
Weir, capped 61 times between 1990 and 2000, predicts Scotland will win by six points against the Welsh in Cardiff, but had hoped Cotter's men would have been approaching the game in better fettle after the 15-9 loss to England at Murrayfield.
"I was quite excited about the team Scotland put out," Weir told BBC Radio Scotland.
"I don't think Scotland could have put a stronger team out against England and the performance didn't live up to it. So let's hope things can change today, but they're going to be up against it because Wales have got a very strong side.

"Wales have got strength and depth on the wings and they've got Dan Biggar playing pretty good rugby.
"But Scotland have got the same; good attacking players like Stuart Hogg and Sean Maitland, Tommy Seymour's come onto a game, Finn Russell if he's on top form can control things and we've got the Gray brothers [locks Richie and Jonny]."
Weir is desperate to see Scotland play more "clinical rugby" after seeing them spurn good opportunities to score tries against England.
"In the England match, when Finn Russell and Stuart Hogg broke through, we have to make these chances stick and score against the bigger sides.
"So if that opportunity arises they have to make the most of it because they can't afford to lose that."
