The former Sunderland man said it is still a work in progress at Anfield, with the fixture at home to Tottenham set to be Klopp's 39th game in charge.
"Over the time he's been here everybody has seen what he's tried to change in different aspects of our game, both in attack and defence and with the mentality of the players. It's still a work in progress and we are still trying to do that on a daily basis together with him."
Mignolet went on to say how Klopp's enthusiastic touchline antics are infectious:
"His enthusiasm and his character was very positive towards the players. You felt he was behind all the players and you could see it in the games. He's playing his own game on the sidelines and that's what you want as a player because you feel he's there behind you and that only makes it easier to play as a player on the pitch."
Mignolet has had his fair share of criticism this season, as he has struggled for confidence amidst a string of less than impressive displays. Another Liverpool star woefully short of form - Christian Benteke, is out of the Spurs clash due to injury, but the Belgium stopper has backed his team-mate to come good:
"It isn't always easy to play every game but Christian's got that mentality to keep his head down and focus on the next game. He will always be ready when called upon."
A win against Spurs on Saturday evening would be a huge boost for Klopp's troops. They have a game in hand over fourth spot rivals - Manchester City, West Ham and Manchester United, and are in desperate need of three points to close the gap.
A run of three Premier League wins in a row was ended with defeat at Southampton, and with Tottenham coming to town, Klopp will have two ensure his players are ready physically and mentally, because this is a game they cannot afford to lose.
