Liverpool boss Rafael Benitez has accused the board of breaking promises made to him before he signed a new contract last year.
Benitez pledged his future to the Anfield club for five more years in February 2009 but is rumoured to be considering his options following a below-par campaign.
Finishing outside the top four in the Premier League and further disappointments in Europe has increased the pressure on Benitez at a time where he has been strongly linked with the managerial vacancy at Italian side Juventus.
Ahead of Sunday's Premier League meeting with title-chasing Chelsea, Benitez has criticised the 'changing conditions' at the club since he put pen to paper.
Last month, American co-owners Tim Hicks and George Gillett confirmed their intention to end an unpopular reign at Anfield by putting the club back on the market.
"I decided to sign an extension because the squad was good and the money was going to be there. But the conditions changed," explained Benitez.
"We've had a bad season and hopefully things will be different in the future, but at the moment I can't talk about the future because I don't know what's going on."
Benitez left former club Valencia in 2004 despite a period of success and added:"I left Valencia because conditions changed.
"It was not a question of my money that I stayed at Liverpool. I said 'no' to other massive offers. I decided to stay under certain conditions and they have changed.
"The players share the same frustrations. I know how they feel because I've been talking to them all season. The season has not been good, that is clear. We know why and what has to change."
