Wales need to beat Matt Williams side and then topple Ireland in Cardiff six days later to achieve their first grand slam since 1978.

The visitors have won just once at Murrayfield in 20 years yet travel to Edinburgh as overwhelming favourites - and their return to form has given Bulloch heart.

Weve seen how far Wales have come in recent times, theyve been a joy to watch this year and I think they are inspirational. said the 29-year-old.

I was at a couple of dinners in Wales a few years ago and they hadnt won a game for a couple of years, much the same as ourselves and its amazing how far theyve turned things round in a short space of times so it will be a great challenge for us.

You look at Ireland and Wales, who we are categorised with in the Six Nations as the Celtic brothers, and it just shows you what you can do if you have a good spirit, a good continuity in selection and work hard in what you believe in.

Weve shown signs that it is going to click. We scored a couple of tries against Ireland, we played well against France and if we can take these moments and just try to build them into one big performance we can turn the corner quite quickly as well.

Bulloch is hoping the familiarity between the players in both sides will be more of an advantage to the Scots, already buoyed by their crucial victory over Italy in their last game at Murrayfield.

He added: We obviously play against the Welsh players week-in, week-out in the Celtic League and we know a bit about them and so hopefully that will stand us in good stead.

They proved against France that they can spring a lot of surprises in the way they played but the fact is we have been used to playing these guys for five or six seasons so I think that is a key advantage for us.

And after the Italy game last week everyone was upbeat, everyone was enjoying training and there was a lot of chatter and smiles about.

Even though we hadnt played that well we actually got that win, I think thats important to build the confidence and hopefully that will forward onto this week.

Weve got belief in ourselves that now weve ground out a win. That might have been the problem against France when we got to the finishing line and it was snatched away from us.''
