Jim Mallinder saw Saints make it five out of five then warned: ‘We haven’t hit top gear yet.’
Two tries from James Wilson and 14 points from the boot of Stephen Myler sealed a 24-6 win against London Wasps at Franklin’s Gardens on Friday night.
It put Saints top of the league ahead of Saturday’s action and maintained their 100 per cent record at the start of this season.
But director of rugby Mallinder believes there is still plenty left in the tank for the weeks and months ahead.
“It’s pleasing to win five out of five, but I don’t think we’ve really reached top gear,” he said.
“There’s still more to come from us.
“Defensively, I’m very happy with how we did on Friday, to keep them out.
“And attacking wise, I think we can just sharpen up in few areas.
“If we can do those things then I’m sure we’ll put a few teams to the sword.”
Saints exerted plenty of pressure in the second half, but despite that, and being a man up for 10 minutes after Tim Payne’s sin-binning, they weren’t able to secure a bonus point.
Mallinder wasn’t fazed, though, and he was simply delighted to see his side get another win under their belts.
He said: “There was a 10, 15-minute period where we should have scored.
“Soane Tonga’uiha went through the middle and James Wilson had a chance to use his 6ft 4in frame to get a hat-trick.
“We probably wasted a couple of opportunities there.
“I’d have loved a bonus point, but overall I’m happy with the win.”
