Tom Hicks and George Gillett have been at odds over the direction of the club for much of the last two seasons, but the bickering has taken a backseat ever since Benitez signed a new contract last month.
The duo's visit came as a July deadline approaches to refinance the loan that funded their takeover of Liverpool two years ago. And the calculators came out early at Anfield after witnessing eight goals on another pulsating night.
Also in the directors' box was Amanda Staveley, who was the chief negotiator for last year's failed takeover bid by Dubai ruler Sheikh Mohammed bin Rashid Al Maktoum.
Staveley negotiated the Abu Dhabi United Group's buyout of Manchester City in September.
Hicks, who has said he is looking for new partners to invest in Liverpool from the Middle East, and Gillett have been assessing their personal financial situations amid the global economic crisis.
Gillett has appointed financial advisers to explore a recapitalization of his assets, which could include the sale of the Montreal Canadiens.
And Hicks' company, which wns the Texas Rangers and Dallas Stars, has defaulted on about $525 million in loans.
