Kieran Tierney has ranked former Celtic boss Ronny Deila among the best managers he has worked with.

The left-back, who is currently on loan at Real Sociedad from Arsenal, also rates Scotland head coach Steve Clarke highly.

But he is particularly grateful to Deila for giving him his Hoops debut. Speaking to The Scottish Football Podcast, he said: "I don’t think I have got an order of who has been best for me or who has been my favourite.

"Every manager who I have played for, I am so grateful.  You look at the start, it would be Ronny Deila. He gave me my debut, so how can you look past that?

"Every one of the managers who I have played for, they are special for different reasons. Steve Clarke for his loyalty and for picking me last season when I wasn’t playing so often and coming on as a sub.

"I would go away and he would start me. He gives me this belief, as well you can see throughout the team.

"He is important to me and I will be forever grateful for that.”
