Former Football League chairman Harris, who has had a hand in
the sales of Aston Villa, West Ham and Manchester City, said due
diligence has already been done.
Harris also claimed the party he was representing was not one
mentioned publicly before.
He added: "A huge amount of work has been done. "It is none of
the groups mentioned in the Press. The ball is now in our client's
court to make an offer.
"I don't think the deal will be done before the transfer window
closes this month but the next pressure point is October, when some
of the RBS loan of £237m has to be repaid.
"It may happen then. But in the present climate these things are
impossible to predict."
Last week Hong Kong-based businessman Kenny Huang — whose
interest was allied to the Chinese government — pulled out of the
bidding process, while Syrian-Canadian Yahya Kirdi's
much-publicised interest has been treated with scepticism.
Harris said history has taught him that those who went public
before an agreement had been reached rarely succeeded.
He added: "The Chinese government involvement was always a bit
far-fetched.
"In any takeover situation, when people resort to announcing it
to the media, you have to question the seriousness of the
offer.
"If the name of the prospective buyer comes out before the deal
is done then probably it is never going to be done.
"Look at when Chelsea was sold in 2003. My firm was advising the
club and we only knew of Roman Abramovich on the Thursday before
the deal was completed the following Tuesday."
Harris worked on a bid for Liverpool two years ago for Kuwaiti
Nasser Al Khorafi, whom it is claimed agreed a deal for £300m up
front and another £100m based on financial performance only to pull
out at the last minute.
Harris said: "He just lost his appetite. No explanation was
forthcoming."
