The Scottish defender has rescinded his contract at Hearts.
Celtic are after a new centre-back this summer as Jason Denayer's loan spell from Manchester City comes to an end.
One name that has been mentioned is Hearts captain Danny Wilson. The central defender has had an exceptional season in Edinburgh, as Hearts cantered to the Scottish Championship title this campaign.
In April Ronny Deila commented on Wilson, suggesting he was 'one of the names' they were considering for next season - as per Sky Sports.
Wilson himself went on to make it clear he was happy to be linked with Celtic, so the former Liverpool and Rangers man certainly looked an option.
Now he is more so than ever. Wilson is officially a free agent as of yesterday. Sky Sports reported that the Scot had rescinded his contract at Tynecastle by activating a clause in his current deal at the club.
Hearts boss Robbie Neilson told Sky of his decision:
“We’ll miss him on and off the park and he’s been a great captain but that’s football; players join and players leave."
Now Celtic have a real chance of signing the player.
But what about those Rangers connections? Would they stop the player considering Celtic?
Wilson, who also spent an ill-fated three years with Liverpool, started his career at cross-city rivals Rangers.
He joined the club in 2006 and remained there until 2010. He made his debut in 2009 and went on to play 26 games for the club - which is what caught the attention of Liverpool's wandering eye.
But he told Sky Sports last month that playing for Rangers in the past would not affect his future decisions on his career:
"I think you’ve got to be open to anything in your career.
"But like I say, right now I’m just focused on Hearts and finishing the season strongly here. We’ll see what happens in the future but you never know."
Perhaps Wilson is Celtic-bound after all.
