Plymouth Argyle bidder James Brent says he is hoping to complete his purchase of the club by the middle of October.
In an interview on BBC Radio Devon Brent was asked if he could complete a sale by 10 October.
"We do have a lot of dependency on other people moving at the same pace, so that date would be challenging," Brent said.
Argyle are still in administration and Brent's bid is one of three formal proposals to buy the League Two club.
As well as Brent's bid there businessman Paul Buttivant and Gibraltar-based property consortium Bishop International, which is backed by Truro City chairman Kevin Heaney, are also in the running to buy the club.
"We're really pressing things forward now as quickly as we can," he added,
Brent says he is gaining hope that a deal can be done every day but acknowledges that there is still work to be done.
"I've got more confident over the past week than I was a week ago but there's still risk in the process.
"It's frustrating having a lot of dependencies on other people, each one of which potentially has veto, but the various stakeholders thus far have been absolutely great and they've been passionate to make sure the club survives.
"I've been very impressed from the beginning with the passion everyone has, it was what attracted me to the club in the first place," he added.
Brent will attend his first ever Plymouth Argyle match on Saturday and intends to sit with fans in the Devonport End, as he watches Carl Fletcher's first match in charge of the Pilgrims against Macclesfield.
