Burt was among the first to be informed by the Rangers manager, Steven Gerrard, that his services were no longer required at Ibrox.
Rangers fans are reacting after a player released from Ibrox this summer turned up at Celtic's training ground on Friday.
Liam Burt was among the first to be informed by the Rangers manager, Steven Gerrard, that his services were no longer required.
Burt later expressed his sadness at leaving Rangers on Twitter, but that message has now been deleted.
And a return to Celtic, where he played before switching to Rangers' youth set up in 2014, could now be on the cards, with The Scottish Sun reporting he will spend the next few weeks training with the Bhoys.
Burt played just three times for Rangers' first team - but never under Gerrard - and had in recent seasons spent time on loan with Alloa Athletic and Dumbarton.
Nevertheless, those of a Rangers persuasion are not best pleased with their former player's recent activity.
This is what they're saying on Twitter...

Liam Burt to them - good prospect, but did not set the heather on fire at Alloa last season so I fully understand why we let him go. No regrets, good luck to him - he could be the next Charlie Telfer!!!— Petrocelli (@caltat) June 21, 2019

Liam Burt going back to them is a weird one on their behalf, he’ll never get a game!— CA (@PC_Rangers) June 21, 2019
Liam Burt wanted to be at Rangers. We didn't offer him a new deal last season as he wasn't good enough.— Andy C (@pipedown27) June 21, 2019
Now Celtic are claiming he "ran his contract down" to move to them. Embarrassing, but expected. https://t.co/w1Enpb8tZv
Yesterday a celtic fan told me there is not player in the rangers squad that would make their squad......today they attempt to sign liam burt after being released from rangers.— aaron ross (@aaronross85) June 21, 2019
Timing is everything
Celtic currently have a vacancy for a young central midfielder like Burt, having released Regan Hendry at the end of last season.
The Rangers goalkeeper, Aidan McAdams, was the last player to make the cross-Old-Firm switch, after leaving Celtic in 2017.
