The Daily Mail reports that Benitez is still unsure if the kitty will be increased if he sells players such as Yossi Benayoun, Ryan Babel, Albert Riera and Philipp Degen this summer.
Both Fernando Torres and Steven Gerrard have been linked with moves away from the club, after the club failed to qualify for next season’s Champions League.
Benitez is desperate to tipe up a £2million deal for Rangers defender Danny Wilson in order not to splash all of his transfer kitty on one player.
