The 28-year old fast bowler, who was let off with a mild warning by the PCB last week, said, "even now I feel the Board has been somewhat harsh by issuing a warning to me and asking me to show more commitment to the team, but I can honestly say commitment for the team has never been an issue for me."
Shoaib, who left for England to join English County Durham, however thanked Khan for believing him.
"The chairman has been very fair to me. I am relieved that the medical commission of the Board has also accepted that I did sustain an injury during the final Test against India due to which I could not bowl," he said prior to his departure.
"I have bowled in the past in some matches with niggling injuries. I have never backed out of a challenge. About my attitude I never try to knowingly annoy anyone," he added.
Akhtar said he did not want to go into the details or dig up old issues and said he had tried his best in the series against India but things just hadn't worked out.
