Celtic are again looking at Reading defender Liam Moore with the Daily Record linking the 27-year-old as an alternative target to Shane Duffy.
Neil Lennon has admitted to tentative enquiries about the Irish internationalists but Celtic and Brighton will be out to extract maximum value from any deal.
Moore was first linked with Celtic in January 2017 but nothing came of that as Dedryck Boyata emerged after the winter break in Dubai to become a regular in the Invincibles.
Like Brendan Rodgers, Nicky Hammond has Reading connections with the Record reporting:
Celtic have put Reading skipper Liam Moore on their transfer wishlist. Boss Neil Lennon is scouring the market as he seeks defensive reinforcements during this transfer window.
Shane Duffy remains a target with Celtic trying to thrash out a deal to take the Republic of Ireland stopper from Brighton.
However, with English Premier League sides West Ham, West Brom and Burnley also involved in the battle for Duffy, Celtic have other options under consideration and Moore is on that list of potential alternatives.
The 27-year-old has been a stalwart for the Royals since joining from Leicester four years ago. He was handed the captaincy by previous manager Jose Gomes, but lost his starting slot in the side at the tail end of last season with manager Mark Bowen opting for younger options.
Celtic have until 11pm on Tuesday to register any new signing for the Champions League qualifier against Ferencvaros it seems unlikely that they will find a ready made defender ready to go straight into the side.
If successful against the Hungarian champions the Third Round Qualifier would be played on September 14/15 which looks a more realistic target to bring in new signings.
Albian Ajeti has had to work hard on his fitness, after 10 days at the club he is likely to be on the bench against Dundee United on Saturday, with Moore and Duffy likely to be in similar situations as they begin pre-season training at Reading and Brighton.
