Rangers fans are devastated Ronny Deila is leaving Celtic in the summer!
Indeed, the Gers faithful have taken to Twitter in response to the club's decision to let the Norwegian go at the end of the season. It's been billed, of course, as Deila's decision...
That means the Celtic boss won't be managing against Rangers next term and many Gers fans have joked that he's running scared after being beaten by them already this term.
Mark Warburton will have a new rival manager next campaign, then, as Celtic look for the Norwegian's replacement.
But Rangers supporters are, on the whole, disappointed. They were looking forward to Deila remaining in the job - as he isn't considered a serious threat at all by Rangers.
Who will succeed Deila - Neil Lennon, Roy Keane, David Moyes, Brendan Rodgers? Here's how Rangers fans reacted on Twitter to the news Deila will leave Celtic...
Ronny Deila will have won every league title he entered. One loss to Rangers and he's gone. #itsallabouttherangers— John DC Gow (@johndcgow) April 20, 2016
@ScotlandSky as a Rangers supporter, I feel sorry for Deila who seemed a decent guy in a job where expectations were too great-wish him well— Scott Sincere (@sincerely4scots) April 20, 2016
@BBCSportScot I'm a Rangers fan, if Lennon gets the job I'm celebrating, he's as bad as Deila— Bobster (@pugilist22) April 20, 2016
The Rangers support absolutely devestated Ronny Deila's leaving Celtic in the summer— Dean (@deanomac54) April 20, 2016

No one wants to lose the title to Rangers in their 1st season back
