Liverpool chairman Martin Broughton is believed to have given four potential bidders until the end of this week to come up with firm proposals to buy the club from current owners Tom Hicks and George Gillett.

Potential bidders will have to prove they can build a new 60,000 seater stadium which was originally won by Laing O’Rourke in 2008.

The contractor started small scale site preparation work but the scheme was soon shelved due to the downturn in the economy.

It is believed the stadium job will be retendered once new funds are in place but O’Rourke will be strong favourite to win the contract.

A source close to the contractor told the Enquirer: “The new stadium has obviously had problems with financing but hopefully a change of ownership will sort that out.

“We won the original job and and are ready to get back on site as soon as the money side of things are sorted out.

“The plans are fantastic and it will eventually be one of the nest stadiums in the country .”

Chinese entrepreneur Kenny Huang is expected to submit a bid worth around £400m to takeover the club.

Three rival bids could come from Syrian-Canadian businessman Yahya Kirdi, New York based private players the Rhone Group and the Kuwaiti Al-Kharafi family.
