JOIN USSwann, 32, made his ODI debut as a 20-year-old way back in 2000 but soon vanished from the scene, dropped after he failed to impress Fletcher.
After seven years, 249 days and 175 England ODI matches, Sawnn, who many a time thought of ending his career, made a return to the international stage and rose to become the No.1 Test bowler this year.
"When I first got picked for England, I was not good enough to play for England. I got picked on the basis of some good limited-overs performance and under-19 trips," said Swann.
The spinner said the seven years he spent out of international cricket helped him to emerge as a better bowler.
"I thank Duncan Fletcher because had I played badly I would have ended up playing one or two Tests and forgotten for ever. So the seven years I spent out of international cricket didn't harm me whatsoever," said Swann.
Asked if he ever got frustrated during those years, Swann said: "If you got better like that, it is very sad. A great fast bowling coach (Ottis Gibson) once told me that (by being ignored) you don't get better you get bitter."
