Liverpool are watching Standard Liege goalkeeper Guillaume Hubert.
The Daily Mail says his emergence has seen a host of Premier League scouts run the rule over the keeper.
Swansea and Aston Villa have also watched the shot-stopper this season.
The 6ft 6ins keeper spent a period training with Stoke during his time with Valenciennes, but they couldn't agree a fee with the French club.
Standard are keen to keep hold of their goalkeeper, but could consider offers starting at £700,000.
