Liverpool accepted a bid from the Hammers almost two weeks ago to make his season-long loan spell a permanent move, however Carroll is yet to seal the move to East London.
The Mirror report:
“The 24-year-old England striker has had his £80,000-a-week Anfield salary paid by the Hammers during his season-long loan at Upton Park.
“But Carroll – who is out injured for up to four months – now wants £20,000-a-week on top of that if he is to make a permanent summer move out of Anfield to east London.”
Carroll impressed during his time on-loan to West Ham this last season, despite missing a large chunk due to injury.
He is also currently sidelined for the summer with a heel problem.
Liverpool will be hoping Carroll can agree terms as quickly as possible to raise the funds for a summer transfer spree.
