Liverpool manager Jurgen Klopp has reportedly identified left-back as an area of his squad that he would like to strengthen in the summer.
It has been suggested that Klopp has decided that Alberto Moreno is not good enough defensively to carry on in that position next season.
According to Bild, the Reds will look to replace the Spaniard with FC Koln's Jonas Hector.
The report adds that the 25-year-old may be available for around £6m.
The ten-time Germany international joined his current employers from SV Auersmacher in 2010.
