Plymouth Argyle bidder James Brent says that talks with the club's creditors are continuing and are 'constructive'.
Mr Brent says he will still decide by Friday whether a bid to take the club out of administration is viable.
Argyle appointed administrators to run the club in March after financial problems which began last autumn.
"I've spoken to all the stakeholders and everyone is very constructive," Brent told BBC South West on Thursday.
"There are a number of stakeholders and clearly to make an acquisition we need definitive agreement, and until we get definitive agreement we can't get it done.
"Rather than quietly confident I'm quietly hopeful.
"It is complicated. It will take weeks rather than days to close something, and until it's done, it's not done.
"I've ended the week happier than I started it. There's no saying if something will blow up tomorrow or Monday that won't become a tank trap, but there's none in sight at the moment."
Mr Brent is one of three people who have approached the administrators to buy the club.
Gibraltar-based property consortium Bishop International, represented by Truro City chairman Kevin Heaney, have put in a formal bid which has yet to be approved by the Football League.
Businessman Paul Buttivant has also put forward a bid to buy the club.
