Mane became a star at Saints after arriving from RB Salzburg in 2014, winning himself a move to Liverpool in 2016.
And Mali international Djenepo, who joined the south-coast club last summer, says he can become better than the Champions League winner.
"Sadio is a big inspiration for me. I like him, he's a very big player," he told talkSport.
"But I think I can be better [than him] if I work hard. Sadio is a very big player, and I'm young and I need to learn more.
"In the future we will see. I will do my best to become the next Sadio Mane."
