"Michael is a player that I recommended to Gary Mills over the summer, when he was released by Wycombe," Richardson told the NEP. "I thought he had been unlucky to be released by Notts in the first place, back in 1996.
"But Gary did not fancy him, which is fair enough.
"I would have been interested in taking him when I took over, but by that stage he had signed a two-year contract with Orient."
Simpson will again line-up against his former club tomorrow in the heart of Orient's midfield. The experienced maestro has a habit of playing well against his former club, though Richardson will be hoping his side can stiffle his former team-mate.
More build-up to come.
