Ryan Jones insists that Welsh fans haven't seen the best of him yet. Jones will win his sixth cap when Wales take on Scotland on Sunday.

But the Neath/Swansea Ospreys forward, who is originally from Newport, feels that he has not yet fired on all cylinders.

He said: "I've played five times for Wales and I think it is about time that I start playing how I have been playing all year.

"I've spoken to Mike (Ruddock) and have been quite disappointed by how I've played so far, I've got a lot more to offer and I want to show that on Saturday.

"In Paris I felt the pressure. There was a lot of expectation and I think that affected me in the first 15-20 minutes but then I started to get slightly more involved.

"It has been a sharp learning curve."

Jones knows that this game is a potential banana skin for Wales but he confident that they can continue their Grand Slam march.

He said: " The pressure is mounting and as the games go on, the more they become key to the success of Welsh rugby.

"It is a massive game and I really hope that we haven't underestimated them, which I don't think we have, because the preparation this week has been exactly the same since day one.

"The Grand Slam that everyone is talking about could so easily be gone and we have to win this weekend, and the way to do that is to impose ourselves early on."

Jones and the rest of the Welsh team are expected to be greeted by around 25,000 Welsh fans in Scotland 68,000 capacity Murrayfield Stadium.

And Jones, who celebrates his 23rd birthday on Sunday knows that could be a key a factor. He said: " Any game you play for your country is a massive honour but this again is massive. "It really does inspire you to think how many Welsh fans are going to be in that stadium.

"On behalf of everyone in the squad I would like to give them a big thank you and it takes a bit of pressure off you.

He added: "I remember after the France game, all the French fans had left and all the Welsh fans stayed behind and that really does help and it could be a key factor at the weekend. It is almost a home game for us.

"Their back row is vital, they do a lot of hard work for the side. Hopefully if me, Martyn Williams and Michael Owen can cope with that then our backs have show that they have the ability to score tries."
