Liverpool are in contact with Olympiakos for left-back Kostas Tsimikas.
The Daily Mail says Liverpool have enquired about Tsimikas amid their continued pursuit of Norwich defender Jamal Lewis.
The Reds had a £10million bid for Lewis rejected by Norwich on Thursday as Jurgen Klopp seeks left-back cover for Andy Robertson.
And Liverpool are weighing up Tsimikas as an alternative target.
The Reds have made an enquiry about the 24-year-old Greek international, who impressed in his side's Europa League defeat to Wolves this week.
