Wilson, 23, started his career with Rangers before earning a move to Liverpool in 2010 at the age of just 18 having impressed at Ibrox.
The centre back struggled to make an impact with the Reds though, and after loan moves with Blackpool and Bristol City, Wilson returned to Scotland with Hearts in 2013, initially on loan before penning a permanent deal just months later.
Having captained Hearts to the Scottish Championship title this season, Wilson has rebuilt his career - but will now leave Tynecastle according to the BBC, who report that Wilson has triggered a clause in his contract meaning he can become a free agent this summer.
That's a huge blow to Hearts, but it could be great news for Celtic after manager Ronny Deila recently confirmed to Sky Sports that he is interested in signing Wilson.
"That is one of many names we are talking about but there is nothing serious in that," he said earlier this month. "But he's a good player."
The report that Wilson is now a free agent could make a deal with Celtic even more likely, especially considering that the Daily Mail had previously suggested it would cost £400,000 to prise him away from Edinburgh.
The BBC do also note that clubs in England and further afield are interested in Wilson, but Celtic will certainly be favourites after Deila's admission that he is interested in signing Wilson, with Virgil van Dijk and Jason Denayer both potentially moving on this summer.
