Man United are reportedly ready to bid in excess of £20m for Southampton forward Sadio Mane.
After missing out on Pedro to Chelsea, Red Devils manager Louis van Gaal is now keen to bring the Senegal international to Old Trafford, and they are ready to improve on the £15m offer they submitted last week.
Saints boss Ronald Koeman said before their Europa League play-off against FK Mitdjylland that none of his squad are for sale, and they are still likely to reject any further bids for their attacker.
Mane scored 10 goals in 30 top flight appearances last term, including netting the fastest ever Premier League hat-trick in under three minutes against Aston Villa in May.
