Balram Chainrai, the man trying to become League One Portsmouth's owner for the third time, has described a fans' bid for the club as having "no substance".
The Hong Kong-based businessman also claimed his firm, Portpin, was the only bidder with the "experience and money to return Portsmouth to its glories".
He said a Pompey Supporters' Trust (PST) bid would fail due to "in-fighting and lack of actual money".
"You can't run a business like that," Chainrai told BBC Sport.
He did, however, admit to being unsure whether Portpin would pass the Football League's "owners' and directors' test", a necessary step if Pompey are to continue to play league football under his control.
