Bothroyd was kicked out of Arsenal as a teen, throwing his shirt at Don Howe after being substituted in a youth cup final. He was sold to Coventry for £1million and also had spells with Perugia, Charlton and Wolves as well as loan stints at Blackburn and Stoke.
He told The Sun: "Everyone knows about the mistake I made at Arsenal.
"It was 11 years ago but people still ask me about it all the time. I still don't know if I'll ever be allowed to forget it. It was a big mistake but you have to learn from your mistakes. I was just a boy. It was a moment of madness. I shouldn't have done it and maybe they should have handled it in a different way. I think even Arsene Wenger has said that since.
"He also said I was one of the most talented youngsters he has worked with and was very happy when I got an England call-up.
"That compliment meant a lot to me because he's one of the best managers in the world and produces lots of good players."
