A group of investors including a member of Kuwait's al-Kharafi business family could revive interest in Premier League soccer club Liverpool if owners lower the asking price, according to one of the investors.

In January, Tom Hicks and George Gillett, Liverpool's American owners, were in talks to sell the club for £500 million ($711.2 million), including debt to the group of Kuwaiti and non-Kuwaiti investors.

Refad al-Kharafi told Reuters his investor group could be interested if the owners were willing to negotiate their valuation, but "it remained a group decision".

"This is a good opportunity if the price is right... If they changed the price, probably investors (in general) will be interested," Kharafi said.

The original negotiations broke down as the price was "not realistic today" given the global economic downturn and lack of liquidity, he said.

"Last time we talked with them was at the end of January. Their price did not change til today. It's not reasonable," he said.

He did not identify the other group members.
