Manchester United could have to double the money they offered over the summer if they want to land the signature of Southampton star Sadio Mane, according to the Daily Telegraph.
United were hoping to bring the Senegalese international to Old Trafford during the summer window (via Telegraph).
However, Saints officials made it clear that the 23-year-old would not be sold, despite United indicating that they would be willing to offer £20m to sign him (via Telegraph).
United eventually laid out an initial £36m on Monaco striker Anthony Martial (via Telegraph) and there is now a feeling that Southampton feel that Mane is now performing to a similar level to the France international and can now comfortably demand a fee in the region of £35-40m (Telegraph).
And The Telegraph states that a striker shortage at the same time that an influx of new television money could drive prices up right across the board, as it will give Southampton the opportunity to not only demand more money but to eventually tie him to a new deal.
