But Simpson is denying new reports linking Dichio, 32, with moves to either Leeds or Stoke City.
"I don't want him to leave and no-one has made an offer for him," Simpson stated.
"There was an enquiry from Dennis Wise earlier in the season, asking whether he could take him on loan.
"At the time I said 'no' and he asked if it was okay if he got back to me in January about it, but I haven't heard anything regarding Danny Dichio.
"He's been involved all the time apart from suspension and he's been a miss for us in the last couple of weeks. It will be good to have him back this weekend."
