"I thought that they did a really good job, I thought that we got a couple of fortuitous tries but on the whole it's great to get the win.
"The goal-line defence was nigh on heroic at times today. I'm really pleased for the lads."

"Probably too many mistakes really, neither side were able to play a lot of football in the conditions.
"We didn't control the middle third of the field and made some crucial mistakes, they capitalised on a couple of quick tries and then it was catch up."
It was a scrappy first-half but Newcastle led 7-3 at the break.
Sale came back fighting and took advantage of Newcastle having two men in the sin-bin. The Sharks scored three tries to secure the win but a serious injury to Marland Yarde may put a dampener on the celebrations.
FT: Northampton 15-23 Leicester
Rob Horne received a standing ovation when he delivered the match ball for today's derby.
The result didn't go Northampton's way this afternoon but the support from the whole club, and Premiership rugby's fans, for this man has been outstanding.

"It was a huge effort and it paid off. I don't know what to say really I can't really remember the game!
"That’s what we wanted. We knew that it would be hard work, particularly with the weather, but it’s fantastic to get a win."
That's an impressive away win for Gloucester - and a bonus-point one to boot.
You do wonder though what might have been if Charlie Sharples' second try had been reviewed when Gloucester only led 23-21.
Wasps were convinced the pass to the winger was forward.
Image source, Getty ImagesIt was an emotion-filled day for Northampton but their opponents took a couple of key chances and then held extremely firm in defence.
There's concern for England international Jonny May after he left the field in the first half with a shoulder injury but overall Geordan Murphy and his outfit will be pleased.
For Northampton it just didn't quick click in the key moments and handling errors and individual errors proved to be costly.
Northampton 15-23 Leicester
George Ford cleared Leicester lines and with Saints in possession once again they're being pushed back.
The visiting side's defence has been really solid and with seven seconds remaining Northampton are running out of time.
Northampton 15-23 Leicester
Off the next passage of play Dan Biggar has the chance to gain key, key metres for Northampton off a penalty. However, he misses touch and will be kicking himself for that one.
Northampton 15-23 Leicester
Once again Northampton struggle at scrum time with Leicester's replacement Joe Heyes showing his power, Heyes is another of the Tigers' England U20s stars.
The Saints do get the ball out, though, and move it to the right. Alex Mitchell can't find a window through and instead the ball is lost out of play.
Rohan Janse Van Rensburg
Sale steal the ball from a Falcons line-out and the backs makes good progress down the field. Rohan Janse van Rensburg receives the ball on the 22 and he blitzes through the Newcastle defence to score Sale's third try.
Lewis Ludlow, con Danny Cipriani
Surely that's now game over?
Lewis Ludlow is driven over by the Gloucester pack for their bonus-point score and Danny Cipriani adds the extras.
Mikey Haywood, missed con Dan Biggar
It's an excellent time to score your second try of the season. Mikey Haywood has only been on the field for a matter on moments and his break out of a maul produces five key points.
Dan Biggar hits the uprights with the conversion attempt, that's the third one that he's missed today.
Charlie Sharples, missed con Danny Cipriani
Controversy in Coventry as Charlie Sharples goes over for his second try of the game in the corner but Wasps believe the pass that put him in from Jason Woodward was forward.
Danny Cipriani took the conversion quickly but hit the post with his effort to prevent it going to the TMO.
Northampton 10-23 Leicester
Northampton don't mess out about scrum time, instead Teimana Harrison flies off the base and makes a beeline for George Ford.
Ford, flanked by a couple of team-mates, does well and halts the forward sort of the line. The Saints swing it to the right before Kyle Eastmond poaches excellently at the breakdown.
Bryn Evans, missed con MacGinty
Sale's forwards make progress from the line-out but Will Cliff releases the backs and it is Bryn Evans who scores in the left-hand corner. AJ MacGinty fails to add the extras.
Northampton 10-23 Leicester
Play is paused for a couple of running repairs, it's a physical old encounter as you'd expect.
Tom Youngs is the man receiving treatment but he's back up and ready to take his place at scrum time. It's Northampton put-in, around five metres out.
Sale 10-7 Newcastle
Sale think they've scored from five metres out but the TMO rules that Byron McGuigan's foot was in touch.
Northampton 10-23 Leicester
Leicester give away a couple more penalties in the red zone, they will need to be very careful now otherwise JP Doyle might reach for his pocket.
Northampton again drive the penalty into the corner and find the mark at the line-out. These are vital moments in this match, a score for Saints would bring them right back but if Leicester hold out then their confidence will soar.

Lennie Newman
Former Northampton Saints player and manager on BBC Radio 5 live sports extra
I've got to take my hat off to Leicester because they are doing nothing but doing nothing really well and are letting Northampton make all the mistakes.
The Northampton attack has been so tepid.
