The civil war that has suddenly gripped Liverpool could determine whether they can ever rejoin the elite of English football, or be condemned to yet more years in the Premier League wilderness.
Manager Rafa Benitez launched an extraordinary offensive yesterday with what he sees as a ultimatum to the club's American owners that they can only interpret as back me or sack me.
In response, George Gillett and Tom Hicks offered a considered and cutting response, apparently designed to call the bluff of the manager who often reacts in an impulsive way to any perceived problems.
Benitez has become increasingly angry in recent weeks over what he believed was a complete lack of communication from the Americans.
He argued that since buying the club they had put their energies into other projects, left Liverpool on a back burner, and wondered whether the pair were working together as a team.
Both men have each been to only one game this season, and Benitez claims he has spoken to them just once in three months, while also exchanging the odd email.
Gillett's son Foster, installed at Anfield as a go-between, has flown back to the States for an extended period.
In particular, Benitez wants the £17million deal for Javier Mascherano wrapped up, after agreeing terms over both contract and fee. The Americans though, have delayed, insisting they have first option on the Argentina midfielder and that there is no need to rush.
Benitez also tried to negotiate deals to bring in two highly-rated young Brazilians, and wants funds to back a major offensive to sign £15m Argentina defender Ezequiel Garay.
All three proposals were met with indifference by a board increasingly sceptical about his constant pursuit of untried South Americans, believing it to be a high-risk strategy that could cost the club millions.
Benitez wants to move quickly, with Juventus interested in Mascherano, and Manchester United in Garay, who, along with the Brazilians, is also wanted by Real Madrid.
His frustration has grown to such a level Bayern Munich and Fenerbache made inquiries after word leaked out at Anfield of his discomfort.
That did nothing for relations between the manager and owners sides, with the Americans beginning to believe they may be better off without someone prone to such emotional outbursts.
There is still anger within the boardroom over Benitez's personal attack on Gillett, Hicks and chief executive Rick Parry over a lack of support after the Champions League Final.
Gillett and Hicks responded by making £50m available for transfers, and believe the manager now has a squad strong enough for a serious assault on the title.
However, the situation came to head yesterday when Benitez was told by the Americans to wait until they arrive in England on December 16, and until then to concentrate on getting the best out of a squad that has cost so much.
That enraged the Spanish, who immediately marched into a press conference conducted in a remarkable manner.
Virtually every question was answered with the same response: "As always, I am focused on coaching and training my team." He repeated the sentence - clearly meant as a response to the demands of the Americans and probably borrowing from a phrase they used - more than 25 times.
Their reaction was swift and significant. They issued a statement that robustly defended their position and also explained what had been happening behind the scenes.
"We made a significant investment in the playing squad during the summer and desperately want this team to succeed," it read. "There are some very important games coming up in the next couple of weeks and all of us need to focus on winning those games and getting the best out of the players we already have.
"We will leave any talk of buying or selling players until we come across to Liverpool in December and sit down with the manager then."
The question for Benitez is whether he can remain in charge until then. The owners have called his bluff, and he must mull over his position after being so publicly chastised.
He would receive a huge payoff - thought to be up to £6m - if sacked, even if he finds another job, but will forfeit that amount if he quits.
He has been bluntly told he has had significant backing and will have to earn further support through results on the field, which have been less than impressive despite major investment.
The ball in now in his court, but the US tycoons are hard-nosed businessmen and Benitez has suddenly found himself on extremely treacherous ground, that could conceivably lead to his departure.
Rafa Benitez has spent £122.7million in transfer fees on 17 players (not counting free transfers) since joining Liverpool in the summer of 2004. Here are his biggest buys.
F Torres (A Madrid) £26.5m
R Babel (Ajax) £11.5m
X Alonso (Valencia) £10.5m
D Kuyt (Feyenoord) £9m
P Crouch (S'pton) £7m
J Pennant (Arsenal) £6.7m
F Morientes (R Madrid) £6.3m
