Chelsea boss Graham Potter insists former manager Thomas Tuchel and former Roman Abramovich have his full respect.
Chelsea's new owners have taken pops in public at both Tuchel and Abramovich this season.
But yesterday, Potter said: "Change is a challenge in any organisation. We have to deal with the new and we have to build things up again because things have changed, things have gone and left.
"That's part of the challenge to come and I understood that things would be difficult from a leadership perspective. It is a challenge, stimulating and ridiculously hard.
"It is probably the hardest job in football because of that leadership change and the expectation - because, rightly, where people see Chelsea.
"I have the utmost respect for Thomas Tuchel and what he achieved here in terms of winning the Champions League, so I can understand that (the chanting).
"What the previous ownership has done before is fantastic. But this is a new era, a new chapter and, we're going through some pain and it's difficult at the moment. Obviously, I understand their frustration, I appreciate their support because there is support there but I also understand there is a bit of pain we have to go through as well."
