The Belgian goalkeeper was in fine form during Saturday's 0-0 stalemate.
Njie came close to opening the scoring in the first half with a well-struck shot across goal with the outside of his boot requiring a top save from Belgian Mignolet to keep the scores level.
And he praised the 'keeper for his great job but was more focused on improving for Spurs’ upcoming games.
"I think first of all we had a good match," he told tottenhamhotspur.com.
"I think the Liverpool keeper did a great job and today we lost two points but now we’re going to work for the coming matches where we’re going to do better and try to get the three points."
The summer signing has had to content himself with a place on the bench so far this season, with fellow signing Heung-Min Son taking most of the limelight in the early games.
The Cameroon international started the game against Liverpool on the bench but was called upon early as Tottenham winger Nacer Chadli was forced off with an injury after eleven minutes.
And Njie admits it is not easy to come off the bench so early in the game - but was pleased to get the game time nonetheless, insisting he and the rest of the Spurs squad are looking forward to their upcoming games.
"It’s not that easy," he added.
"We waited for the match with our plan but sometimes an injury happens. It’s always good to come into the match but now we are looking forward to the coming games."
