Christian Day is refusing to get carried away with Saints’ big win against Bath and instead believes his side have plenty of improving to do.
Day scored twice to help Northampton secure a superb 43-25 success against their top-four rivals at Franklin’s Gardens on Saturday.
But he was disappointed with how Northampton dealt with the scrum, which was one area Bath managed to dominate.
And the influential lock says he and his team-mates must improve if they are to see off in-form Harlequins at the Gardens on Friday night.
“The easiest thing to do when you’re winning is think you’re a hero and nothing changes,” he said.
“We’ll be having a real hard look at ourselves, particularly the forwards at the scrum. We were disappointing there on Saturday and we need to learn some lessons quickly as a pack and get things right.
“On the whole on Saturday, we were pretty excellent everywhere else. We’ll put the game to bed and look ahead to a smiliar sort of challenge against Quins on Friday.”
Day felt Saints’ 18-point winning margin was fair at the end of an enthralling encounter.
But he was keen to stress the result will mean nothing if his team don’t continue to build on it as the season goes on.
“The score was a reflection of how the game went,” said Day. “They deserved a few tries and we deserved a few more.
“It’s not really important at this stage of the season. The important thing is to perform well, play well and get wins.
“At the end of the season it’s two one-off games and from Saracens away last year we know it’s not necessarily who finishes top who wins.”
