Coventry scored four goals in the top flight for the first time since a 4-1 win over Sheffield Wednesday in May 2000 to back up their victory at Nottingham Forest before the international break.
Those around the Sky Blues’ training ground in Ryton feel they will have a platform to stay alive if they compete over the next seven games.
A trip to Tottenham and a trip to Fulham – both winless – follow, with games against Sunderland, Everton, Crystal Palace, Leeds and Ipswich before December.
“It’s huge and we have to use it in a good, humble way,” said Lampard, whose Coventry are currently 14th.
“We have to be excited and I can see players developing very quickly.
“A lot of players had little or no Premier League minutes, Jack Rudoni, [Brandon] Thomas Asante, [Ephron] Mason-Clark, lots of them.
“So is it human nature in the first few games where we go against the two best teams in the league (Arsenal and Manchester City) and we come up against Brighton and go: ‘hmm, it’s not easy here’?”
“This [win] gives good confidence, so it’s a balance of overconfidence and overconfidence. But when you get a result at that level, it’s great to have a template of feeling.”
It could be a defining six weeks for Lampard’s men after an impressive, if not perfect, win against Newcastle.
Coventry’s previous home games saw them lose 1-0 to another promoted side, Hull, before beating Brighton 5-0.
They lost 3-1 to Aston Villa in the Carabao Cup, making it imperative that they find their form at the CBS Arena.
“We’re going to be relatively weak in almost every game,” Lampard said. “So we have to maximize everything and be at the limit, and I thought we were at the limit in a lot of ways.
“They’ve got to keep their feet on the ground because the next one, the one after that, is going to be tough. But we look like a team that’s going to be tough for teams to come here. We haven’t had that feeling in our first games on CBS this season.”
