Stuart Hogg went over for a try

Stuart Hogg, Peter Horne and Ali Price crossed for Glasgow with Rory Clegg adding two conversions.

Alex Cuthbert and Rey Lee-Lo scored Cardiff's converted tries with two penalties from Gareth Anscombe and one from replacement Steve Shingler securing the Blues first league win against Glasgow in 11 meetings and their third successive victory this season.

Gregor Townsend said he was pleased with the effort which went in but was disappointed with the result.

Speaking to glasgowwarriors.org, Gregor said: "To come back from 13-0 down and play some really positive rugby in the second quarter of the game was good to see.

"We created opportunities to lead the game, but over the 80 minutes we didn't do enough to win and lost focus on a couple of occasions.

"There was a lot of effort in the second-half and it was a really competitive game. Both defences worked hard and the contact area was full of bodies, and as a consequence it was often difficult to create quick ball.

"But credit to Cardiff as they played well throughout the game and held firm when we had a lot of possession in the second-half.

"We knew going into the game that they have a quality squad that are very well organised. Tonight they selected three opensides in their backrow so they were competing hard at every breakdown and they had some dangerous runners in their backline.

"I thought our ball carrying and work to support the ball carrier in the first-half in particular was very good."

Warriors had to shuffle their pack during the game with Tim Swinson and Alex Allan both having to play at flanker.

Gregor said: "Josh Strauss was playing really well and gave us a lot of go-forward too. It was great to see him back, so it was a blow for him and us that he had to go off.

"Lewis Wynne stuck in really well, he had a couple of good carries and defended well while Alex Allan had to fill in at blindside flanker to replace Tim Swinson who had moved there from the second-row. It's not ideal but you've just got to adapt to those situations."

Next Friday the Warriors take on Ulster and the head coach says they have a lot of work to do ahead of that clash, which will be shown live on BBC Two Scotland.

He added: "We're obviously disappointed that we didn't come away with the win after the effort we put in and we've got to re-group for next week's game.

"We have recovering to do because that was a physical game. We'll have to make sure that next week we're back working to improve because we have another huge challenge next week against Ulster.

"We are facing another in-form team that shows just how contested the GUINNESS PRO12 is going to be this season."
