Fraser Brown is determined to pay the Glasgow support back after suffering a capital loss.

Heading through to BT Murrayfield with a 1872 Cup first-leg win, Warriors struggled against their Edinburgh rivals to go down 20-8 on the night in front of a bumper crowd of 15,810.

Not only did the result inflict the first defeat on the Scotstoun club by their rivals in seven matches, it was also enough to hand the cup to Alan Solomons' team, while allowing Glasgow to slip off top spot in the Guinness Pro12.

And hooker Brown did not mince his words as he and his Warriors team-mates attempt to restore normal service against Scarlets this Friday under home lights.

He said: "It's huge having a home game next. A big support followed us through to Edinburgh and we let them down. It's not the Glasgow they are used to seeing or the one that we are.

"We felt we could have worked harder and been more clinical. We need to put that right, not just this week, but also in the two European games.

"I don't know if we would say the title pace has slowed down. It's one match in a 22-game season. Munster lost to Connacht, so there are always going to be games you will lose. The most important thing is to come out on Friday and put things right.

"We may not have played our best rugby over the last three or four weeks, but we were just winning those games. It's important we go away and have a really good week's training and we show the determination, passion and workrate we are used to putting in and make things right."

A piece of brilliance from Niko Matawalu seemed to offer Glasgow a way back into the tie courtesy of a try just a few minutes after the interval. But it was a break they failed to build on as Edinburgh held their nerve for a famous and deserved victory.

Brown was honest in his assessment of how Gregor Townsend's men performed on the night against their rivals from the east.

And he was clear in his view that improvement must, and can be made, before Scarlets arrive at Scotstoun.

He said: "Our set-piece aspect was disappointing. Scrum-wise we started off well, but then came under pressure. We probably struggled with that last week and it's hard to put your finger on it after a game because you are quite emotional.

"It's the same with our line-out as they defended it very well. When you have a team who puts pressure on you like that and you make a little mistake like your throw is a bit under or your lift is not quite right, then you'll lose the ball.

"We'll spend a lot of time putting it right for Friday because there is no doubt we are a better set-piece side than what we showed against Edinburgh.

Brown added: "It's just a case that our set-piece didn't function as we would have liked. You just need to drop two or three per cent and it makes a difference.

"Over the last five years we've had it right, and it can only be fixed by hard work. We need to fix those little errors."
