It was just terrifying … even the fact that they knew I was involved in Celtic (football club), they knew where I lived, they knew my family.

It took me 35 years of being involved at a decent level of football to become manager at a great club like Celtic.

It's been draining for everybody, and it's a tribute to the commitment of everyone involved with the club that we've come this far.

It was very difficult to do, but you knew in the back of your head that you had to do it, that you couldn't tell anybody,

When I signed for Celtic I did say to them that it would be best for the club and myself to maybe look at things in the summer but they were quite keen for me to sign for the extra year, which I did eventually. But I will look at things in the summer and see how my hip is bearing up. I'm due to go back to the hip specialist in the summer. It's important to be fair to myself and the club if it is affecting me.
