Andy Carroll says he will only make the move to West Ham if he can receive a pay rise to £100,000 per week as Liverpool attempt to offload the striker.
Carroll is currently on a salary of £80,000 per week, which the Hammers have been subsidising during his loan spell with the east London club.
While West Ham submitted a bid of £15.5 million to bring Carroll to the club permanently last week, which was accepted by Liverpool, the move still hasn't been completed.
But now the Mirror have claimed that the reason behind Carroll's hesitation in signing a deal with West Ham is that he wants to get a promise from the club to make him a top wage earner.
But the paper also reports that West Ham are hoping to reach a compromise with the England international, and believe that it is likely they will do so by the end of the week.
Carroll has had a difficult run since his £35 million move to Liverpool in the January 2011, with the striker suffering from both poor form and limited playing time at the club.
His move to West Ham was sealed deadline day last summer, despite Brendan Rodgers continually insisting that the striker was in his plans for the season ahead.
Part of the perceived issue with offloading Carroll was the fee which Liverpool would demand, with the club hoping to get as much of their £35 million back for his sale.
But in his season at West Ham, which offered an opportunity to shocase his talents, the 24 year old only really came good towards the end, with injury troubles hampering his success at the club.
Because of this, Liverpool have accepted that they won't get back their outgoing money, but with the 2014 World Cup to think about, Carroll will need to be careful of making huge demands on clubs who are willing to offer him game time next season.
