Speaking post-match, the back-rower said the support of the 18,000 strong in the crowd who "carried" the side through for a last-minute victory in Round 3 of the 21/22 Premiership campaign.
"It's amazing, they carried us through until the very end," said Liebenberg."
"We are so fortunate to have these supporters back with us, they lift us up and they provide so much energy."
Looking back on the match Liebenberg, who was named captain of the Tigers side for the match, admitted the visitors were the dominant side in the opening half but praised the "fight" of his Leicester team-mates to keep the chances of a win alive.
"They dominated the first-half, which was obvious, but we came out fighting in the second-half," he said.
"We stayed in the fight and got over the line at the end.
"We knew it would be a set piece battle today and turned up for one another in that area and across the pitch, like we knew we would have to against a world-class outfit like Saracens."
Pressed on the ladder position after three rounds, the Tigers forward said it was for others outside of the club to discuss as the focus for Leicester squad remain on what was to come and not on what had come before.
"It isn't something we will take much notice of, to be honest, as it's always been about the next game," replied Liebenberg.
"Where we are on the table is for others to look at and talk about, we will just get on with the next job together."
