The 16 year-old is an England U16 international and The Sun says only paperwork needs to be rubberstamped before the move is complete.
Hardy has been involved with Derby U18s since he was 14 years of age.
As he is on scholarship forms, Hardy is clear to move to another English during the season and outside the transfer window system.
The teen posted to social media yesterday: “After almost a decade at Derby County, the time has now come for a new chapter.
It’s been an incredible nine years here. I just want to thank everyone at the club who has supported me throughout my journey and helped me to become the player and person I am today.
"I’m grateful for all the memories I’ve made throughout my time at the club and the lads I’ve played alongside, I wish everyone at the club the best for the future."
