Pietersen told England chiefs that either Moores was axed or he would quit as captain - a stance which led to both losing their jobs last Wednesday - but maintains that he went through the correct channels to make his case.
"Nasser was quite taken aback to know I had actually had a number of face-to-face meetings with the ECB," added Pietersen. "I think everybody probably thought I was holding a pistol to the ECB's head.
"It wasn't like I was stating 'I want this, I want that, I need this, I want that'. I had five or six meetings with the Board and I knew my next meeting was going to be the day I got back.
"Something was leaked, I don't know who by, I would love to find that person."
