Senegalese sensation Saido Mane was a reported target for Manchester United in the last transfer window.
The Red Devils made a bid of around £20M which was turned down by the Saints hierarchy.
According to the Daily Telegraph, United as well as other Premier League clubs interested in Mane will have to double that amount if they are to get their star target.
Mane’s value has doubled with his fine form so far this season notching in 4 goals in 11 matches in all competition so far this season.
Southampton boss Ronald Koeman is a big admirer of United Dutch international Memphis Depay, it would be interesting to see if United can tempt Southampton with a player plus cash deal for the pacy and tricky attacker Saido Mane in the January transfer window.
