Lots of Newcastle United fans have taken to Twitter to voice their thoughts at the latest news to emerge from the Tyneside club.
Is this a good appointment for the Toon?
The club did state Caldwell has only taken on the role on a temporary basis until the club finalises its recruitment process to find a permanent replacement for Hogg.
Caldwell will take charge following Monday’s season opener against Reading as the U23s face a trip down to Birmingham City next week.
Toon fans flocked to the tweet from the Tyneside club to share their thoughts at the appointment of 39-year-old Scotsman.
What exactly did these Newcastle fans have to say?
“This is probably my worst nightmare ever. Could only be worse if he replaced Steve Bruce…or would it be? That would be some laugh, actually.”
Going by the reaction of these Toon fans, it would seem the news is not exactly what they wanted to hear after Sunday’s disappointing result against David Moyes’ side.
