He admitted that last campaign, which saw Mane and Liverpool struggle for form as Jurgen Klopp's side finished third in the Premier League, 17 points behind champions Manchester City, was the worst of his career.
But Mane told the Liverpool website that he and his team-mates feel refreshed and rejuvenated after an extended summer break.
He said: "It's always important as a player to have a break because I can say since I came to Liverpool this was the first time I have had four weeks or more of holiday, so that sometimes helps a lot.
"I could see from day one that everybody was looking sharp, which for me was unbelievable! I am not complaining about having one or two weeks' holiday, but it's always extra (helpful) for us to have this long period of holiday."
