Dan Biggar admits it is "a strange feeling" for Wales to enter the final weekend of an RBS 6 Nations Championship with no silverware at stake.

Wales, Six Nations champions during Warren Gatland's coaching reign in 2008, 2012 and 2013, can realistically finish no higher than third this time around.

That mid-table outcome is a direct product of crushing defeats against Ireland and England, when Wales conceded 55 points in total and failed to score a try.

It has rendered Saturday's Millennium Stadium appointment with Scotland as meaningless in terms of trophies, although both teams will target a winning send-off prior to testing summer tours.

Fly-half Biggar's return for Rhys Priestland is among six changes from the side beaten 29-18 at Twickenham last Sunday as Wales look to defend a 12-year unbeaten home record against Scotland.

"I think the last time was 2010 when we did not have anything to play for on the last weekend. It's a strange feeling for us all," Ospreys playmaker Biggar said.

"Obviously, we want to finish as high as we can, so we need Ireland to do us a favour and for us to play well to finish in the top three.

"I suppose we are playing for a top three position and a bit of pride and to give our supporters something to shout about.

"It is an international Test match at the end of the day, and we won't need any pumping up.

"We have been inconsistent as a side this season. I don't think there is any getting away from that.

"We peaked for the last World Cup and it was a superb achievement by the lads, followed by a Grand Slam, followed by a Six Nations (title), so I think we have in Wales been spoilt a little bit.

"We have lost a couple of games. Our form has been relatively good overall, although this tournament it's been a bit disappointing, but we will be back."
