Liverpool owners Fenway Sports Group insist the club is not for sale after a report in the Daily Mail claimed the cousin of Manchester City owner Sheik Mansour recently failed in an attempt to purchase the team.
The report states that Sheik Khaled Bin Zayed Al Nehayan was exploring a takeover in the past year that valued Liverpool at £2 billion ($2.6 billion).
A source confirmed to ESPN FC that Sheik Khaled, who is an Emirati member of the ruling family of Abu Dhabi, was interested in taking over the Premier League club, but ultimately it was not believed to be a credible bid.
FSG, who also own the Boston Red Sox, purchased Liverpool back in October 2010 in a deal worth £300 million.
In response to the Daily Mail's report, a Liverpool spokesperson said: "FSG have been clear and consistent: the club is not for sale.
"But what the ownership has said, again clearly and consistently, is that under the right terms and conditions we would consider taking on a minority investor, if such a partnership was to further our commercial interests in specific market places and in line with the continued development and growth of the club and the team."
FSG, according to sources, have a long-term relationship with American investment firm Allen & Company, who provide advice on business and financial issues.
Part of their working relationship includes Allen & Company's role in filtering and vetting inquiries regarding club investment opportunities such as Sheik Khaled's.
However, sources say Sheik Khaled's approach did not go beyond discussions with Allen & Company, as it was not deemed to be worthwhile of being presented to FSG.
FSG added that they receive a large amount of interest regarding investment opportunities within Liverpool.
