Manchester United hope an expected offer from a Qatari consortium will lead to a bidding war.
The Red Devils owners, the Glazer family, are looking to sell the club this year.
Per The Mirror, United are hoping to fetch 6 billion, while the Qatari investment group values the club at around 4.5 billion.
Sir Jim Ratcliffe, the chief executive of INEOS, is also interested in buying the club.
United will not be owned by the same Qatari group as Paris Saint-Germain, per the source, if the Qatari bid is successful.
This offer is said to come from another group of private investors, not the sovereign state wealth fund.
