According to the Daily Mail, Celtic have set their sights on signing Hearts captain Danny Wilson this summer, as they start to prepare for life without Virgil van Dijk.
Van Dijk has been superb ever since his 2013 move from Groningen, and his performances mean a summer departure is likely - and the Daily Mail report that with Sunderland and Southampton still holding an interest in the Dutchman, Celtic have started making contingency plans.
They believe that Celtic will target a move to sign Hearts centre back Danny Wilson as a possible replacement having impressed in the Scottish Championship this season.
Wilson, 23, may be familiar to some Bhoys fans having come through the ranks with bitter rivals Rangers, but played just 26 games before earning a big move to Liverpool in 2010.
Just nine appearances for the Reds led to Wilson returning to Scotland, initially on loan with Hearts before penning a permanent deal in 2013.
Wilson was a mainstay of Robbie Neilson's title-winning Hearts side, captaining them to promotion back to the Scottish Premiership this season.
Yet with just one year left on his contract at Tynecastle, Wilson could be up for grabs for just £400,000 this summer, and the Daily Mail believe that price tag could tempt Celtic into a bid, but no talks have been held between the two clubs over a deal.
It would be a real shock to see Wilson sign for Celtic giving his history with Rangers, but he certainly got his career back on track with Hearts after that failed spell with Liverpool - and at worst, he would offer Celtic depth in a position where they could lack bodies if van Dijk leaves and Jason Denayer heads back to Manchester City at the end of his loan deal this summer.
