Scott Hastings says it is time Scotland did themselves justice when they face Six Nations leaders Wales at Murrayfield.
Scott Hastings believes there will be a "sting in the tale" in the battle for the Six Nations title but warned Scotland must "find their mojo" to have any chance of derailing Wales' Grand Slam bid.
Wales will take to the famous Murrayfield turf on Saturday sitting pretty at the top of the table after beating England in Cardiff, while back-to-back defeats have left Scotland down in fifth spot.
England are just two points adrift of Wales with two matches to play, while Ireland are three behind the leaders and face Warren Gatland's side on the final weekend.
Hastings does not believe it will be all plain sailing for Wales as they attempt to dethrone Ireland, but the former Scotland centre says Gregor Townsend's men will have to raise their game if they are to put a spanner in the works.
He told Omnisport: "Gatland and Wales will know Scotland are going to come out absolutely fighting for every inch of the turf at Murrayfield and they still have to go home and play Ireland.
"What a bumper finish it could be to the championship. If Scotland were to blow Wales open then the whole championship is back on to be played for.
"I still think there is going to be a sting in the tale in the Six Nations, whether Scotland are going to be involved in that I don't know. They will certainly be underdogs, but they must seek that to their advantage and try and deliver a performance that Scottish rugby is crying out for."
Ex-British and Irish Lion Hastings believes Scotland have gone backwards after finishing third last year and says they must show what they are capable of.
"I think they have regressed a wee bit. They are going to have to find their mojo and find it against Wales. Wales are not going to make life easy so Scotland have to try a dictate a game, take their opportunities." he added.
"They showed in the last 20 minutes against France they can create opportunities, they have a bit of firepower off the bench. It needs a far greater performance than what has been delivered so far."
