The Reds have limited options on the left side of their defence, where England right-back Glen Johnson was often forced to fill in last season as Anfield flop Paul Konchesky was loaned to Nottingham Forest and yester day sold to Leicester City

Reds boss Kenny Dalglish has found it difficult to solve the problem position so far this summer as top transfer target Gael Clichy opted to join Manchester City , while Newcastles £15m asking price for Jose Enrique has proved a stumbling block in agreeing a deal.

Dalglish will now turn his attention to Kadlec, who was the subject of a scouting mission last summer by Liverpool before former boss Roy Hodgson signed Konchesky.

The 26-yearold Czech Republic international is only under contract with Leverkusen until 2013 and has refused to confirm that he will sign a new deal,

The German outfit value Kadlec in excess of £6m, a valuation based on the fullbacks impressive form last season as he helped the club finish runners-up in the Bundesliga.
