Former Liverpool co-owner George Gillett has been sued by lending firm Mill Financial for allegedly breaching a guarantee to pay back $117million (£73million).
The Daily Mail reports the Colorado-based former Liverpool co-owner had borrowed the money in 2008 for investment in the Premier League club, but has failed to pay it all back, despite it being due in August.
A 12-page legal document was filed in Manhattan's New York state court yesterday, and Mill Financial included a copy of an unlimited guarantee to pay the money back signed by Gillett.
The company, based in Springfield, Virginia, reportedly refinanced a loan used by Gillett and Texas business partner Tom Hicks to buy a significant stake in Liverpool in three years ago.
According to the lawsuit his company, Gillett Football LLC, borrowed $70million (£44million) from Mill Financial in January 2008.
The loan became due on August 13 but had not been paid in full, claim the company.
