Murrayfield has not been a happy hunting ground for the Welsh in recent years and they have managed just one victory - a 34-19 win in 1997 - in two decades of trips to the Scottish capital.

But Wales are brimming with confidence after their stunning win over France in Paris and a triumphant storming of Murrayfield will leave Ruddocks side one win from a first Grand Slam since 1978.

An estimated 40,000 Welsh fans are expected to make the pilgrimage north - and Ruddock called on them to turn Murrayfield into a home from home.

It will be good if we can get a huge level of support into the stadium, said Ruddock.

Traditionally we have had a lot of fans coming to Scotland - not all of them make the game, but we are hoping a huge number do.

Having that level of support and seeing the red jerseys in the crowd would be huge for us. The boys have really appreciated it so far, we had great support out in Paris last time up and in Rome.

Wales boss Ruddock backed Scotland counterpart Matt Williams to pull through the difficult period the Scots are encountering - though obviously not starting on Sunday.

We have got a huge regard for the Scottish rugby team. Their win against Italy takes the pressure off them so they can come out and attack us, said Ruddock.

I have a huge regard for Matt Williams because we worked together at Leinster so I know his qualities as a coach and as a guy.

But there will be no sympathy on show on Sunday.

We have really tried to talk about what we want to achieve as a team. I try to create a positive psychology in the team where we are looking forward to the game, but not fearing it,'' said Ruddock.

We respect the opposition but are not fearing a big Test match and we give the players a chance to play a good brand of rugby, which has been our strength.

But we also have to make sure that when we have to, our organisation and team spirit is in place so we can defend crucial periods.''
