Harris is among football’s most influential powerbrokers and are working on the sale of Newcastle and Everton at the moment. He has was the man responsible for brokering the sale of Chelsea to Roman Abramovich in 2003.
Liverpool has a massive £350 million debt that could force them to sell their best players, according to Harris.
The Reds’ owners George Gillett Jr and Tom Hicks have an option extend the January 25 deadline for repaying the loan by six months.
But reports suggest that their main lenders, Royal Bank of Scotland and Wachovia, could decide not to grant Liverpool an extension.
Both companies have been hit hard by the global economic crisis.
“The one that worries me is Liverpool,” said Harris, the former chairman of the Football League.
“Royal Bank of Scotland and Wachovia are two of those that have suffered. Whether they want to lend it [the money] again or not, they may not be able to.
“If the banks won’t finance, you have to raise equity. If they can’t find it, it’s a brave banker that would repossess Liverpool Football Club.”
“There is no progress at all [on Everton],” Harris added. “The demographics of Liverpool as an area are not hugely compelling. It is not a very wealthy city and Everton share the city with another club which has been in the vanguard for the last decade. They both have a stadium to build, so the economics need a lot of looking at, whereas Newcastle is a one-club city with a fabulous stadium.”
