'Love you till I die' - New Gunner Tierney pens Celtic emotional letter

Emotional Kieran Tierney has poured his heart out to Celtic and their supporters after his Arsenal move was confirmed.

The left-back sealed his £25million move to Arsenal on Thursday and took to Instagram to hail everyone who made his 15 years with the Premiership champions side so special.

Tierney broke through to the senior side under Ronny Deila in 2015 and hasn't looked back since.

His form at Celtic caught Arsenal's attention and the Gunners have made the man, who lives and breathes everything green and white, a Premier League player.

The Scotland international admits he's finding his big move away hard to come to terms with but hopes to keep his incredible bond with supporters despite his exit but admits it break his heart if his special connection was lost.

He posted on Instagram: "This is coming from the bottom of my heart!

"I don’t know how to even begin to put the last 15 years of my life into words... what you as fans have given me and my family

"I cannot repay you in any way possible and for that I am sorry. From the age of seven I was lucky enough to play for the club I love and will continue to love till the day I die no matter what happens.

"Every single second of my Celtic career was a dream and I gave my all every single time I stepped onto that pitch, it’s honestly the least I could do for everyone involved at the club.

"There is to many people to thank individually so I don’t even know where to begin.

"Every single coach and staff member who has helped me on my way to getting where I am today I am so grateful for all the hours help you put into me making me a better player and a better person.

"My team mates have been the best I could possibly have asked for what a bunch of legends man who I’ll be supporting until the end. Where can I start with the fans? I tried my best to represent you every time I went onto that pitch.

"The relationship we had together and the memories we created and history we made was incredible.. I will cherish every single second of it.

"I hope we can continue to have a relationship although I understand that will be never for some people which is heartbreaking for me but I understand the emotions surrounding this situation. It has been the hardest day or two of my life and I really appreciate every single message of support from you all.

"This was not easy in any way shape or form.

"To end I'd like to mention the special relationship I had with the ultras who I have grown up with from BHOYS and Green Brigade.. the atmosphere yous create to help the team is massive and it helped me so much over the last few years..

"I thank you so much for these times together what we have achieved as a club the last few years isn’t possible without you and all the fans.

"This is not nearly enough of what I am feeling but I literally cannot put into words with the emotion I’m feeling towards you all but I hope I showed you every game that I was lucky enough to play. God bless."
