The former Southampton man says it is the desire and professionalism shown in training which is key to the club's form.
"For sure, they [the club's supporters] only see what we are doing on pitch every single weekend and the success as well," Mane told Liverpool's website .
"But the work starts with yourself at home professionally and hard work on the training ground.
"You can see, every single day from day one when I came to Liverpool , players want to improve more and want to get better and better.
"You can see the gym one hour before training is completely full.
"I think that's a very, very big sign for the club because everybody wants to play and everyone wants to be the best. I think that makes things special.
"From the training ground, everything starts there and it's just really important. It's normal that fans are getting so excited to see the team playing well and being successful.
"That's why we are working every single day."
