Rudiger explained that he has been a subject of abuse on the social media just for the wrong accusation about the sack of Lampard as Chelsea manager..
He told chelsea club website: “I have been in the club into my fourth season and I have had four different coaches, with Tuchel now.
“And it was never talked about when Sarri left the club or when Conte left the club that players were involved or something like this.
“My conscience is clear. I know who I am and I know I did not do all that nonsense that came out and for me in my head, I am very free.
“I am open for every new coach, as I was opened also for Mr Lampard.
“I cannot control people’s emotions but people should be human beings. Me, I didn’t post anything but the racial abuse was immense.
“This makes me stronger because I know who I am, I can look in the mirror and I can smile. I know I didn’t do anything so for me this is forgotten.
“For me in life it is very important I can look in the mirror, I see myself, I know who I am.
“Of course it hurts but in this case I just block it out because I know I didn’t do anything.”
Rudiger, who’s back in the squad, has played in every game led by the new boss Thomas Tuchel.
Sheffield United will host the Blues on Sunday night against a backdrop of escalating online racism in English football.
And there have been calls for social media companies to do more to stamp out racial abuse before it can occur.
Rudiger expressed that nothing will change until the abuse have financial implications on those in power.
He added: “To be very honest I don’t know about all these social media things but I think the more people who make accounts, they make money off it.
“So me personally, I think they don’t really care because as you know, this money has power so the rest doesn’t matter, so it is hard to tell if people will make a change on that.
“I feel sorry for that but I feel more sorry for people who are not strong enough so it really affects them.
“Of course it affects me in a way too but it is just in a way that makes me think that people are not normal, people I am sorry to say are just stupid.”
