It was always going to happen – but Alex Dyer admits it still wasn't easy to give up his role as Scotland assistant.
The Kilmarnock boss has fully turned his attention to the Ayrshire side, admitting it wouldn't be fair on anyone to keep both jobs going.
He said: "It’s a big wrech. I love working with the gaffer [Steve Clarke] and working for Scotland. It's been a proud moment, but this is my true calling and I have to make sure I do this right and concentrate 100 per cent.
"I don’t want to let anyone down at Kilmarnock or at Scotland.
"I spoke to Steve Clarke and we had a good chat about it.
"He was brilliant about it, he understands and he gave me good advice.
"He knows I’ve got to concentrate on this, it would be unfair to be on Scotland duty and not be here where I am needed.
"I have got a good assistant, but it wouldn’t be right.
"Andy Millen could take charge any time, but it wouldn’t be right as this is my job."
He added: "It wasn’t an automatic decision, but I always knew that if I got the Killie job it would be hard for me to do both.
"It wouldn’t be fair for Killie or Scotland, it wouldn’t be right.
“I don’t want to go there and be thinking about Kilmarnock, especially when we’re in the Betfred Cup.
"We have to concentrate on those games, the cups are important for us. We want to do the best we can in those games."
