Kenny Dalglish has only been to Anfield once since his axing by Liverpool.
He stressed that was because of circumstances, but he also admitted it was unfair for him to comment on Brendan Rodgers' short reign.
"The last thing people need is for others to be giving their opinions," he told the Daily Mail.
"If you want to be manager of any club you have to adjust to the job.
"You just have to adopt whatever attitude you think is right whatever club you go to.
"And once you're in, if you don't adapt to it you are still going to have a problem, Liverpool is not exclusive in that."
