Inner Circle Sports have joined Liverpool's push to find new owners.
The New York-based investment bankers are one of the six parties currently negotiating with Barclays Capital as the Merseysiders seek an end to the boardroom turmoil, says the News of the World.
Inner Circle does not have the funds to buy Liverpool directly, but their vast contacts could bring in investment.
In 2007 they introduced Tom Hicks and George Gillett to former Kop chairman David Moores.
Inner Circle, run by Robert Tilliss, the former MD of JP Morgan Chase Bank, list Real Madrid, the Boston Celtics and the New York Mets among their former clients and played a key role in Wembley Stadium.
As yet, no official offers for Liverpool FC have been made.
