Liverpool are being linked with a string of left backs, with Aston Villa defender Stephen Warnock one of those on the radar.
The England international was close to an Anfield return in January, with Liverpool boss Kenny Dalglish failing in his efforts to solve the left back problem before the transfer deadline passed.
With Paul Konchesky loaned out to Nottingham Forest and poised for a permanent exit in the summer, a host of potential replacements are being lined up by the Merseysiders, with the Daily Mail claiming five are on the shortlist.
Damien Comolli, director of football strategy for Liverpool, is working on finding the ideal replacement, with Nacho Monreal, Jose Enrique, Emilio Izaguirre, Maynor Figueroa and Warnock the final candidates.
Warnock, who left Liverpool for Blackburn back in 2007, has progressed considerably since that time and moved to the Villains for a fee reaching £8 million back in 2009.
The Reds were thought to be keen on bringing the player to the club on loan originally, but it's thought that Liverpool could go back with a permanent offer at the end of the season.
