Mignolet has said a lot has changed since Klopp arrived on Merseyside a month ago.
Klopp endured his first defeat prior to the international break at the hands of Crystal Palace but was unbeaten during his first six games in charge as he gets to grip with the challenge ahead of him, while his side are in the quarter-finals of the League Cup and on the brink of qualifying from their Europa League group.
Mignolet told Sky Sports: "In that month a lot has changed. He's there and I think he's already improved us a lot. There's a lot of things changed but we look forward to the future."
There have been signs of improvement from Liverpool certainly but there are one or two problems that still remain. They have only managed to score more than one goal under Klopp in one game since his arrival, while there is still the problem of individual errors and not being able to deal with set pieces.
Liverpool will look to bounce back from their defeat to Palace after the international break when they travel to league leaders Manchester City.
Mignolet added: "It's very important, it's a huge fixture as well and we look forward to that one. After the international duty we will make sure we prepare ourselves the best we can."
Given the current predicament that Liverpool are in when it comes to injuries - especially at centre-half and up front, they will do very well to come away from the Etihad Stadium for something to show for their efforts, and will be huge boost for them going forward for the rest of the season.
First of all they would like their players who are out on international duty to return to the club unscathed.
