Man-of-the-match Finn Russell on BBC One:

"The boys were awesome today. It was always going to be a tough game, especially with both teams coming off a loss. I'm so proud of the boys.

"We knew if we were in the game at half-time then we would be good enough and we dug deep. 

"I've got Greig's boots on and I was happy to keep the scoreboard ticking over with my kicking today.

Scotland captain John Barclay speaking on BBC One:

"We started the Championship really well at home against Ireland, we were disappointed against France but we believe within the group that we can do something.

"We recovered from a poor first half to beat a good Welsh side.

"We tightened up in the second half, the tackle area and we've got some backs who can mix it with anyone and we gave them some ball.

"We believe we can beat England if we play like we did in the first half."

John Barclay does his post-match interview to the backdrop of chants of "Scotland! Scotland! Scotland!".

Lee McKenzie asks him if Scotland will beat England next time out.

That nearly takes the roof off.

"We'll take a look at them," says Barclay with a twinkle in his eye.

It comes down to creative opportunities and scoring tries. Wales didn't do anything in attack in the second half.

It was a fantastic second-half performance. 20 unanswered points, and not just the Scottish attack, but the defence was outstanding.

The second 40 was everything this Scotland team has developed into.

Finn Russell has been named the man of the match. Any arguments? He has been impeccable with the boot, converting all seven of his chances to land 19 of Scotland's points from the tee.

That Gregor Laidlaw-shaped void? Filled.  

What the stats don't show us is the impressive way the Scotland fly-half has led his team around the park, orchestrating Wales' demise.

That was a fantastic second-half performance. To play the way Scotland did was a radical change from the first 40 minutes.

We've had a lot of dark days here at Murrayfield, so I'll celebrate.

Full credit to Scotland they really deserve this. Composed in the second half, and they've been clinical.

The ball is booted into the stands and Scotland's players alternatively drop to their knees and punch the air.

What a performance from the hosts. Streetwise, gritty and ruthlessly efficient.

Wales come forward in search of a consolation.

But the crowd are counting down the clock.

And John Lacey awards a final penalty Scotland's way!

Phil: What have Wales been doing in training the last two weeks? Poor handling, no leadership, individuals not a team.

Niels Jan-Gellhoedt:  What an enjoyable afternoon if you are wearing blue.

Matt Jones: Why does Howley wait until 65-70 mins to make changes? No chance for Davies to have impact. Bigger choices sooner, Wales.

Dan Biggar has been strangely quiet today, and it's not often you say that about him.

Finn Russell is announced as man of the match over the Murrayfield tannoy and the crowd approve.

This is a famous win. Scotland that have frustrated Wales at every turn and shown their only showbiz sparkle when they have got within striking distance.

Wales are not going to get three scores in the next few minutes. 

Scotland deserve this result, having come out in the second-half and clearly learnt their lesson from the first 40 minutes.
