Portsmouth owner Alexandre Gaydamak confirmed on Sunday that he is keen to sell the club, dpa reported.
A South African consortium has been linked with a takeover, while a representative of Ukrainian billionaire Rinat Akhmetov confirmed to Deutsche Presse-Agentur dpa he had been approached as a potential buyer by representatives acting for the Premier League club.
"I have come to realize over a period of time that I can no longer invest the time required to oversee the running of the club," Gaydamak told the Sunday Mirror.
"I think it's only right to consider the sale of the club to a group or individual who can come in and invest the time and money to ensure the club reaches its true potential.
"First and foremost, it is far more important for me to find the right buyer - with the club's best interests at heart - rather than sell out at the first opportunity."
That, he suggested, meant an owner who is prepared to fund the construction of a new stadium so Portsmouth can leave their dilapidated Fratton Park home.
