Mane had been viewed as a marquee summer signing by the German champions having starred in the Premier League for the Reds.
Sky Sport Germany have reported that Bayern are expected to sell Mane this summer following a troubled campaign, where he has only scored 12 goals.
Mane was involved in a post-match altercation with Leroy Sane following the club’s 3-0 defeat to Manchester City in the first-leg of their Champions League quarter-final last month, which left his team-mate with a bloodied lip.
Bayern responded by dropping Mane for their next match and handing him a £250,000 fine – which is believed to have been a club record.
Reports in Germany have suggested only Premier League clubs are likely to be able to afford Mane’s £17.4million salary.
