Liverpool unveiled a new sponsorship deal with Asia-focused bank Standard Chartered this morning, estimated to be worth up to €90 million over four years.

Financial details were not disclosed but the tie-up is expected to be worth over €20 million per year for the London-based bank's logo to replace Danish beer brewer Carlsberg , who have sponsored Liverpool since 1992.

Liverpool said the agreement would begin next July and run until the end of the 2013-14 season.

The windfall comes as a timely boost following a pre-season in which manager Rafael Benitez has been frustrated in his attempts to free up cash to spend in the transfer market.

The Spaniard fell out with Tom Hicks and George Gillett over the side's transfer policy shortly after the North American businessmen purchased Liverpool in 2007.
