Arthur was sensationally ditched just days out from the first Ashes Test, apparently paying the price for a 4-0 Test series loss in India, a poor Champions Trophy campaign and a lack of player discipline.
This last was highlighted by an incident in which Warner punched England's Joe Root in a Birmingham bar following a Champions Trophy defeat.
"It was probably another thing that was gutting, that I may have played a part in that," Warner said yesterday.
Speaking on the eve of his departure from London, Warner, 26, spoke of his devastation at not being selected to play the first Ashes Test, saying he "kind of broke down" when he told his mum.
"(It's) massive to miss a Test. As a kid growing up, you want to play in the Ashes and after that incident I went back to my room and I was pretty shattered for a week and a half, two weeks. I still feel the guilt of what happened. I feel myself it's led to me being in this situation at the moment," he said.
