Fabio Capello has reportedly claimed that he was "insulted" by the FA following his resignation as England coach on Wednesday night.
The FA recently stripped John Terry of the captain's armband without Capello's consultation.
"They really insulted me and damaged my authority," he told Italian media.
"What really hit me and forced me to take this decision was the fact the much-vaunted Anglo-Saxon sense of justice, as they are the first to claim that everyone is innocent until proven guilty.
"In Terry's case, they gravely offended me and damaged my authority at the head of the England side, effectively creating a problem for the squad.
"I have never tolerated certain crossing of lines, so it was easy for me to spot it and take my decision to leave."
Harry Redknapp has been installed as the favourite to succeed the Italian.
