Klopp's Liverpool side have lost just one out of their last 19 Premier League games - form that has propelled them into a position to challenge Manchester United for second place.
The Anfield outfit are virtually guaranteed a Champions League quarter-final spot, leading FC Porto 5-0 after a sensational first-leg performance.
"The team spirit is good and the confidence is here so I think we are in a good way," Mane told Liverpool's official matchday programme.
"Every single player is always very happy playing with each other. We always try to help each other and we work as a team.
"I think that is the team's power and the team's purpose. Every single player would love to play in this team.
"We are lucky boys and we are going to keep trying to work hard and give our best when we take our places on the pitch to continue to try and win the games.
"I can sense that the club is moving in the right direction. There were a couple of difficult years at Liverpool a while back but those things happen to every single club in the world.
"At the moment we are in a good way so everything is possible. I think we have improved a lot in the past few months.
"We know that on our day we can beat any team in the world."
The Senegalese international was also full of praise for club-record signing Virgil van Dijk, who became the world's most expensive defender in January after sealing a £75million move from Southampton.
"He's a great player and I know him very well because he was my team-mate when I was at Southampton too," Mane added.
"He is a very good addition for us and we are very happy to have him in the team. For sure, he will make a difference for us.
"He is strong and technical and clever in the games. He wins a lot of balls in the air and he reads the game very well too."
