Benetton Treviso captain Antonio Pavanello
"I think we have to take the positives out of our performance even though we did not win.
"Ulster showed their worth and why they are where they are in the table but I thought we played well against them.
"We have been affected by the international call-ups but with the squad we put out I
Dragons 20 v 6 Munster
The Dragons inflicted just a second defeat of the season of Magners League leaders Munster at a wintry Rodney Parade.
The home side controlled the first half and should have been further ahead at the break than 17-3.
Tom Riley and Gavin Thomas crossed for first half tries for the Welsh side while Jason Tovey kicked ten points. Tovey and Toby Flateau impressed in front of the home crowd while Munster's only scores came from the boot of Paul Warwick.
Newport Gwent Dragons head coach Paul Turner
"I am really happy. I thought we controlled the game, we out muscled them in the contact area and our set piece was very good.
"Munster are top of the table and to beat them you must dominate the set piece and upfront and we did that.
"Conditions were difficult out there tonight but I was really pleased with our second half display. We didn't get much on the score sheet but we didn't let them either and that is good."
Munster head coach Tony McGahan
"Firstly I'd have to give credit to the Dragons.
"They played well and their work at the break down was excellent. They kicked very well, used their possession and took their chances.
"Hats off to them, we can't have any quibbles or offer any excuses."
Edinburgh 24 v 19 Connacht
Edinburgh survived a late flourish by a spirited Connacht side to take the victory at Murrayfield.
Brian Touchy crossed twice in the early stages as the Irish side established a deserved early lead.
Chris Paterson responded with a penalty and converted try by half-time.
A Tim Visser try put Edinburgh in control in among kicks from Paterson, David Blair and Connacht's Miah Nikora and Ian Keatley
Edinburgh head coach Rob Moffat
"It wasn't a classic was it? We didn't get any rhythm into our game at all and only played in fits and starts. But it was a win."
"It wasn't our best performance of the season, and there are a number of things we'll have to improve ahead of next week, but that was a game where we could easily have slipped up and we managed to avoid that.
"I was delighted with the way (Chris) Paterson performed.
"He's been playing some great rugby this year, and he took his try really well. To go past 700 Magners League points is testament to how impressively he has performed year-in, year-out for this club, and we're extremely fortunate to have someone of his consistency and ability on our side."
Connacht head coach Eric Ellwood
"We're disappointed we didn't win the game.
"We have a great start scoring two tries and even in the last few minutes we had opportunities to finish but we didn't. But we will take the positives out of the game.
"The last couple of times we've gone to Murrayfield we've taken a bit of a hiding so this really shows how far we've come. The guys have really stepped up to the mark, Brian Tuohy, Eoin Griffin, Dermot Murphy, these guys are doing the business and putting their hand up for selection and it's great to see it"
Cardiff Blues on the attack against Glasgow Warriors
Blues 38 v 6 Warriors

Michael Paterson and Richard Mustoe rounded off the victory and Sweeney added 18 points with the boot. The visitors' points came from two Colin Gregor's penalty.
Cardiff Blues director of rugby Dai Young
"It's still frustrating because I still don't think we're playing anywhere near how we can.
"We left it until the last minute to get the bonus point and we certainly would have been kicking ourselves if we hadn't come away from today with a bonus point.
"We played a lot of rugby and a lot of rugby from deep.
"We're trying to build our game and we're producing opportunities and not really nailing them.
"So I'm pleased we got the bonus-point win, but we've still got a lot to do."
Glasgow Warriors coach Sean Lineen
"With three injuries and 14 other players not available to us, that is 17 players out and we just do not have the strength in depth, which showed out there.
"In terms of representing Glasgow there will be changes next week because some of these guys clearly have not got the stomach for the fight. We are really disappointed, but there is a home game against Treviso next week and I'll put 15 guys on the field who want to play.
Tavis Knoyle on the charge
Aironi 17 V 34 Scarlets
A brace from Morgan Stoddart helped the Scarlets move to second place in the Magners League table with a bonus point victory over Aironi.
The Welsh side scored three of their four tries in the final ten minutes after the hosts had raced into a ten point lead.
Tito Tebaldi scored 12 points for the hosts including a try, Gabriel Pizarre also touched down for the Italians.
Fourteen points from Rhys Priestland alongside tries from Jonathan Edwards and Gareth Maule saw the Welsh side home.
Scarlets Head Coach Nigel Davies
"This was an important win for us and it was pleasing for us to achieve a bonus point victory away from home in terms of our Magners League campaign and it could be significant for us later on.
"We didn't control the game as we would have liked, and in the first half we didn't have the lion-share of the game as we did out in Munster, so that's something we'll be having a good look at.
"But it's encouraging that the belief building in this team meant that the boys remained calm, focused and didn't panic when the score-line was tight - we were under pressure for large parts of the game but when our opportunities came, we took them very well.
Ospreys 19 v 15 Leinster
The Ospreys came out on top in a repeat of last year's Grand Final at a freezing Liberty Stadium.
The visitors outscored the Magners League champions two tries to one but a penalty try and 14 points from Dan Biggar were enough for the Ospreys
Andrew Conway and Isa Nacewa crossed for tires for Leinster.
Ospreys head coach Scott Johnson
"It wasn't a great spectacle, but the result was nice to have.
"It wasn't a great performance and when you have a young group of players like this they often lack the experience and fortitude to close off games.
"I think it will be great for their development and good for the momentum of the squad. We will take the win, but there will be an honesty call as well."
Leinster head coach Joe Schmidt
"I felt that we created more of the play and more chances, but with a little bit more positivity we could have had even more of the play.
"I didn't feel as though they'd score and I was pleased that we broke down their defence maybe half a dozen times.
"We're disappointed with the result but really proud of how the young guys played again.
"We have a short five-day turnaround before traveling to Wales again to face the Scarlets and we, like the Ospreys, have won two out of three games in what is a very tough period."
