Celtic boss Neil Lennon is upset for Steve Kean over his abuse from Blackburn Rovers fans.
Lennon, who also knows Kean, believes the Rovers boss seems to be in a no-win situation.
He said: "For me, it seems like he has never had the chance to do his job properly. For whatever reason, the support have never taken to him.
"I know Steve from being on a few coaching courses and I know his assistant Iain Brunskill, who was with me on the Pro Licence.
"They are good football guys. At the end of the day it is a results-driven business and I just hope they start picking up positive results because there is a danger they could get detached from the rest of the clubs there.
"But in terms of the treatment, it's not on, it's not fair and I would hate to work in an environment like that.""Even when they were winning games like the other week, there was no pleasing supporters then.
