The Teranga Lions, coached by Allou Cisse, a member of the historic class of 2002, who reached the World Cup quarter-finals has lavished praise on the Reds superstar.
"Mane is unique and cannot be compared to any other Senegal player. He can make the difference," Cisse told reporters, as quoted by BBC Football.
"He's already one of the best - you can't say he's not. He plays for one of the most iconic clubs, one of the best in Europe, and he's top-notch for them.
"He's absolutely unique because he is so unpredictable, that's what makes him great."
Cisse, who spent four seasons in the Premier League with Birmingham and Portsmouth, admits the countries attacking talisman hasn't changed one bit since his lucrative move to Merseyside.
"Despite everything that has happened for him over the last two years, he hasn't changed - he's just as humble as he was when I first met him at the 2012 Olympics.
"Senegal isn't only Sadio Mane, though, he has a good team built around him and I think it should be a little plus for him that we're all behind him."
