Rick Parry remains defiant amid the bitter war of words that has engulfed Anfield, with the Liverpool chief executive claiming he "has a duty to the fans" to stay at the club.

Parry's comments come after another blistering attack by Tom Hicks, the club's co-owner, who described his tenure as a "disaster" this morning and reiterated demands for his resignation. Hicks, whose relationship with his business partner, George Gillett Jr, has disintegrated over recent months, claimed Parry has taken the club backwards but the club's chief executive appears unmoved by Hicks' latest broadside, instead preferring to focus on the "job in hand".

"I don’t think there’s a discussion between chief executive and co-owner," Parry said. "Apparently there has been some entertaining television which I haven’t seen."

He added: "There needs to be a resolution between the owners, in the meantime we are focusing on trying to run the club."

Despite tensions between rival factions in the club’s hierarchy continuing to escalate, Parry insists that Hicks was in no position to ask him to leave the club.

"It’s a matter for the board," he said. "I report to the board. If the board want to talk to me about resigning I will talk to the board - that's it."

Less than a week before Liverpool's Champions League semi-final against Chelsea, Parry was keen to concentrate on matters on the pitch.

"We’re trying to get on with the football, which is why I’m still here," he said. "There is a job to be done. There are big matches to be played. That’s where the focus should be - this is a sideshow. You know the focus is on getting things right at the club. There's a job to be done and I have a duty to the club."

Parry was responding to another scathing attack from the Liverpool co-owner, in which he reiterated calls for the chief executive to resign.

"Look at what's happened under Rick. It has been a disaster," Hicks said. "We have fallen so far behind the other leading clubs. We should have the stadium built by now. We have a few major sponsors when we should have 15.

"We have still got the top brand in the world of football but that's no good if you don't know how to commercialise it. Rick needs to resign from Liverpool FC. He has put his heart into it but it is time for a change. You have to be able to work with the manager and Rick has proved he can't do that."

In the wide-ranging interview, the American businessman admitted he had never heard of Jurgen Klinsmann before approaching the German to take over from Rafael Benitez, claimed he wanted to extend the Spanish manager's contract and insisted he will buy the club from Gillett despite the present impasse.

Hicks said: "George became good friends with [Klinsmann] a year ago.

"I get this call from George out of the blue in which he says 'have your people do their research on Klinsmann'. He and Rick set up the meeting in New York. I did go to the meeting along with my son, Tom.

"Rick Parry had already met with Jurgen alone for a couple of hours when we arrived. We all then spoke to him for another four hours. Afterwards I told the truth to a reporter who asked the question and suddenly it is 'Tom Hicks tried to get Jurgen Klinsmann'. George initiated it but we all participated."
