Brendan Rodgers insists he understands Celtic fans' anger towards him after his move to Leicester.
The 46-year-old joined the Foxes on a three-and-a-half year deal on Tuesday after walking out of Parkhead.
A banner was unveiled during Celtic's 2-1 win at Hearts in midweek calling Rodgers a fraud while a video shared online showed supporters chanting abuse at their former manager.
He said: "I've seen what's been said but Celtic supporters will hurt, I understand how they feel. They are hurting and maybe a little worried in terms of what might happen with me leaving.
"Words, you always have to be careful with. I've seen the banner, the Celtic supporters are hurting. They gave me everything so I'm not going to say anything other than that."
Rodgers continued: "It was a shock and they are probably angry but eventually reality will set in and the work we did will be appreciated.
"But what gave me the comfort to move is what we put in place there was going to stabilise the club going forward.
"I knew, coming away, the improvements made will hopefully allow that success to continue.
"It may be a little unfair on Leicester, I haven't swapped coming into a mediocre club.
"It's recent history has been incredible, they have that ambition to push higher than where we are."
