The Senegal forward joined Liverpool from Southampton in 2016 for a fee of around £34million and has been a glittering success on Merseyside.
Louis van Gaal had been keen on signing Mane in 2015 and the former Red Bull Sazlburg winger wanted to move to Old Trafford.
However, Southampton refused to listen to offers and told Mane to stay at the club for a further season.
The Saints allowed Mane to move the following summer and he claims he held talks with United before being persuaded by Jurgen Klopp to join Liverpool instead.
Yes, I was really, really close because I even met up with them. So I was coming, I was there and I spoke with the boss who was there before (Van Gaal), Mane told the Mirror.
They made an offer, but in the same week, Klopp called me. He said: “I think its the right club. The right coach for me, and I think its better that I go to Liverpool. For me I think it was the right time as well. I said, “I am going to Liverpool.”
