The team's director of rugby told BBC Sport: "In many ways that was the most satisfying win we've had this season. Gloucester, Bath and Quins in a row was a tough ask, but it's been the manner of the way we started, we've played some decent rugby along the way.
"We've got off to a flyer, but Northampton look incredibly impressive. It's not about how you start, it's about how you end.
"We just always want to be there or thereabouts and put ourselves in the frame for the top four, but we never look too far ahead."
Saracens are the only team in the Aviva Premiership with a 100% record.
