Peter Grant has responded to fellow Celtic great Scott Brown's personal attack on him.
The 60-year-old was a coach at Parkhead under Tony Mowbray when Brown was in the early days of his playing stint at the club, first made captain during Mowbray and Grant's stint.
The fiery ex-midfield general revealed on the Open Goal podcast that he had "no time" for Grant because he had "zero personality" and claimed he would have left the club had the former Norwich boss stuck around.
It came in a chat around Brown turning down the likes of Tottenham Hotspur and Newcastle to stay at Celtic.
Grant got the chance to respond on the Go Radio Football Show and said: "Everyone is entitled to their opinion. I've absolutely no problem whatsoever. It doesn't concern me in the least. I've had a lot of criticism through my career, so I've got to have a big backbone.

"Everyone's entitled to their opinion. I'd never tell anyone what to say or what they think of me. I've got a hell of a lot of friends who would say the opposite, but that's life. We move on from it."
Asked if he can pinpoint where Brown's grudge comes from, he went on: "I'm trying to think when it was, it was when I was at Celtic, so 10/15 years ago or something? I've not got that memory, obviously he does.
"It doesn't concern me in the least. If it was Roy Aitken, Danny McGrain, Paul McStay or the great Tommy Burns, it would maybe concern me.
"I've never, ever been critical of somebody who's criticised me. That's life, I've had plenty of criticism. One thing is, I will sleep well in my bed tonight. That's for sure."
Brown's quotes on Grant were: “Lenny came in and we started winning games and the momentum changed from when Tony was there.
