Skysports.com understands Liverpool are lining up a move for Inter Milan's Esteban Cambiasso in case they lose either Xabi Alonso or Javier Mascherano.
Reds boss Rafa Benitez is fighting to keep hold of midfield duo Alonso and Mascherano with the pair being strongly linked with moves to Spain.
Big-spending Real Madrid have openly declared their interest in Alonso, while Barcelona have refused to rule out a bid for Mascherano.
Benitez insists the pair will not be leaving Merseyside, but he is thought to be drawing up possible replacements in case he loses one or both of them with Cambiasso thought to be at the top of his wanted list.
Cambiasso has established himself as a key player for Inter since his arrival from Real Madrid in 2004 and Jose Mourinho would be loath to lose him.
Benitez is thought to be a big admirer of Cambiasso and could step up his interest if he loses either of his two midfield stars before the close of the transfer window.
