LONDON (AFP) - Tom Hicks is set to "formally request" Liverpool co-owner George Gillett approve his bid to sack Rick Parry after describing the club's chief executive as someone with "an inability to manage".

Earlier this week Hicks wrote to Parry requesting he resign as Liverpool's stunning Champions League quarter-final victory over English rivals Arsenal was overshadowed by the latest twist in the series of boardroom spats this season that have mocked Liverpool's reputation for keeping things 'in-house'.

Hicks is reportedly unhappy with Parry's decision to side with Gillett in the increasingly bitter power struggle between Liverpool's feuding owners.

He also believes Parry has failed to close transfer deals wanted by manager Rafa Benitez and fallen short of delivering sufficient merchandising revenue.

Hicks wants to buy out Gillett after falling out with his business partner but the pair, brought to Anfield by Parry, have been unable to reach an agreement, leading to a stalled takeover bid from the Dubai Investment Company.

And with both Hicks and Gillett each owning 50 percent of the club, an ongoing stand-off between the two men over Parry's future seems set to continue unless one of them has a dramatic change of mind.

Nevertheless Hicks told Britain's Sunday Mirror tabloid: "I will formally request George's approval to terminate Rick's contract.

"If he chooses not to, the record will be clear."

Hicks also told the Mail on Sunday tabloid: "Rick Parry has been Liverpool's CEO for 10 years and we haven't won a league championship under his leadership. Our commercial revenues have not kept up with other top clubs during that time, which has made it very difficult to compete for the Premier League.

"After watching him operate, I came to the conclusion it was time to ask him to resign, due to his inability to manage an organisation, his seemingly arrogant attitude to our supporters and his lack of communication with Rafa."

Hicks said he'd decided Parry had to go some time ago and said he hoped a new chief executive could be installed as soon as next month.

"I reached my decision a few weeks ago but waited until after the games against Everton and Arsenal. It is important to try to have a new CEO in place by May so we can begin working with Rafa on player transfers," added Hicks.

Parry, formerly chief executive of the English Premier League, has defended his time at Anfield by saying: "I stand by my track record in English football and as chief executive of Liverpool Football Club. It would be inappropriate for me to comment in detail on these allegations - that should be a matter for the Liverpool board.

"In fact, I would welcome an opportunity to discuss these matters with our co-owners and board colleagues. This continuous airing of issues in the media is clearly not helpful at this crucial stage of our season."

Liverpool won the Champions League in 2005, the fifth time the Merseysiders had lifted the European Cup, and were losing finalists last season.

But the last of Liverpool's record 18 English titles came in 1990, two years before the creation of the Premier League.
