For the second successive week, Scotland fought back admirably after looking like being on the end of an embarrassing scoreline at Twickenham, running in three tries of their own to add gloss to a 43-22 defeat.

That was a passionate display from the players out there,'' Williams said.

''The way their effort and commitment kept up, even though the game seemed lost, they came back again and again, ran the ball from their own try-line so I thought that was absolutely first rate.

But the former schoolteacher admitted: What we are not getting is 80 minutes of constant, world-class rugby. We are getting it in patches, sometimes for a half, against France and out there was different. We had patches when we lost concentration and missed the tackles.

We also had patches of really high-quality rugby, with and without the ball, so its the consistency of 80-minute performance we have to work on.

Thats what the Welsh have done this tournament, they have had a lot more consistent performances than any of the other sides.''

If Williams is given the time, he is confident he can do the job.

He claims he is now putting in the sort of foundations which former Wales coach Steve Hansen provided before being succeeded by the all-conquering Mike Ruddock.

We are bringing in new players, we have brought in new conditioning systems, new sports science systems and we are delivering in patches in games but at the top end, internationally, the improvement from nine to 10 up the scale takes a long time,'' he insisted.

It is not something anyone can deliver in a very short period. We have proved in this tournament we are delivering it in patches.

The consistency will come, thats just a fact of coaching.

Im sure Steve Hansen is sitting back home in New Zealand enjoying that Welsh win. A lot of the work that went into that was done two years ago.
