Saving special praise for full-back Ben Ransom and centre Taylor, Gustard highlighted the importance for his side's young players to grasp their first-team chance with both hands.
And having obviously impressed, against a high-quality opponent, Gustard insists the 38-21 success may change a few negative perceptions about his side's attacking threat.
"It was brilliant, wasn't it, absolutely brilliant. Some of our youngsters really came to the fore," said Gustard.
"Ben Ransom was really instrumental in that first half and he's been on good form for Bedford this season and Duncan Taylor, a local boy come good.
"It's really pleasing, Saracens often get criticised for not playing good attacking rugby, but we've shown that we do.
"I think Ben is such a good footballer with brilliant feet, he's got that ability to beat defenders with aplomb. I think he's one of those guys that can play anywhere in the three-quarters.
"There was a little bit of getting complacent in the second half. Knowing Leicester and the culture and the players they have got, and the strength of the squad, and of course their coaches, they are a difficult team to beat at the best of times.
"Fortunately for us I think we allowed them to come back into the game rather than letting them dominate it. We stepped off a few tackles and it was our mistakes."
In contrast Leicester head coach Richard Cockerill admitted taking away some pride was of little consolation at Goldington Road.
He added: "We did some OK things, we battled hard and got ourselves back into the game but at 27-0 you can't do anything. Those two soft tries at the end of the first half are the difference in the end.
"It would have been a slightly different game if it had been 13-0 at half-time but that's life. We made the mistakes and credit to Saracens.
"We were trying to play and chase the game but then they went and scored.
"They defended the phases well but you need to manage that better and you need to put the ball in the air against that slope and slight wind but we didn't.
"I told them the game's lost but you have to pull your fingers out, grit some teeth and get on with it and come away with some pride, which in the end was about all we got."
