Despite claiming a 19-15 victory over Glasgow that keeps alive their qualification hopes, Northampton scrum-half Lee Dickson knows there is work to be done.
Sunday's win saw centre Harry Mallinder cross in the last play as Saints beat the Warriors in a thrilling Champions Cup game at Franklin's Gardens.
But it could so easily have been a defeat for Northampton as several penalties gave Glasgow kickable points, which is a work-on for the squad.
"I think we started the game really well," skipper Dickson told SaintsTV. "The first 10 minutes we put them under a bit of pressure, made good use of our driving maul and Tei (Teimana Harrison) comes off the back of it and scores.
"We allowed our discipline to slip after that though, which isn't good enough. Defensively we were good, but all of Glasgow's scores came through penalties. We know that at the top level, when you've got world class kickers, you’re going to get punished
"We have to take a real look at our discipline – if we don't it could get us into real trouble."
