"I think other people will make more of it than I will," he said, "but it's never been about me, it's about the team that goes there. I know what I'm going into.
"I'd like to think the sensible supporters might think: 'He's done all right.'
"Myself, Ian Culverhouse and Gary Karsa gave it a right good run for its money. The sad thing is that people don't really know what's been going on.
"Some managers go back and get great receptions. Brendan Rodgers the other week, with Swansea, for instance.
"Others go back and they are the worst thing since sliced bread.
"So I don't know whether I'll get any flak...it's a hard one to call whether they want to do it or not. You'll probably hear it.
"But then at Celtic I played for a club for eight years that half of the city hated.
"You know, I still get it to this day when I go home. I still get the odd shout in the city centre - and I retired about 15 years ago.
"When you have been in that you can handle anything.
"So, I can't say too much more because of the arbitration, but it should never have come to this."
