Kieran Tierney loves Celtic – we all know that.

It appears he still loves former boss Ronny Deila too.

The Arsenal star appeared on Motherwell defender Declan Gallagher’s Twitch stream this week, playing the popular game Call of Duty: Warzone with his Scotland international teammate.

Midway through the action (52:28), while waiting on the latest round to start, Tierney fires up with the song about Deila that did the rounds when he was in charge.

“We’ve got a boss called Ronny Deila… and if you’re feeling blue, I’ll song this song for you, Ronny Deila is Celtic through and through.” etc. You know the one.

A supporter made a clip of it on Twitter if you’re not one of those unfortunate souls who can navigate Twitch.

Yes, it’s definitely the kind of thing that would seem fake or some sort of Twitter joke, but remarkably it isn’t!

 

Deila was of course the man who gave Tierney his Celtic debut after being impressed with the then-teenager during training at Lennoxtown.

Tierney has told the story about that before when appearing on Open Goal.

He told Si Ferry and the gang: “They eventually gave me a deal, I was buzzing. When I was 17, people ahead of me were making squads and playing games but one day they all travelled with the 20s.

“John Collins came in and needed another body for training, I went up and Deila loved me, after the session, he shook my hand and all that.

“That was the start of the season and by Christmas, I was training with them every day. Ronny Deila said to me you’re going to start against Partick Thistle, but I broke my leg before I could start.”

Tierney would eventually go on to make his debut under Deila against Dundee in April 2015, becoming a regular the next season and keeping his place in the team until his exit to Arsenal in 2019.

Deila didn’t quite make himself a legend of Celtic, struggling in cup competitions and in Europe, but he delivered league titles during his tenure and oversaw the development of eventual key talents like Callum McGregor and Tierney.

He was a huge part of our nine-in-a-row run.

It sounds like the former Celtic left-back will always be grateful to his former boss.
