Former Portsmouth owner Sulaiman Al Fahim says he is part of a Middle East group bidding to buy the stricken club.
Al Fahim, who had a short spell in charge at Fratton Park in 2009, revealed his involvement in the consortium on Twitter.
"Yes I am involved, I hope the offer is better than other bidders," he wrote.
Pompey have been in administration since February and remain threatened with liquidation unless a buyer can be found.
Fans' group the Portsmouth Supporters' Trust and another former owner, Balram Chainrai, also want to take over at the npower League One club, with both parties having until the end of this week to finalise their bids.
But administrators PKF are now considering an offer from the new consortium.
