He may have been a few feet away in the opposite dugout last season, but Spireites first-team coach Chris Morgan is this year planning Sheffield United's downfall.
The Spireites kick-off at 1pm on Saturday against the Blades at what is likely to be a sold-out Proact and after over a decade as a United hero, Morgan admits he's not expecting too many pleasantries from the away end.
"I'm sure there won't be any if we go in front!" he said. "I had 12 and a half fantastic years there and it's a club that will always be in my heart, but now I'm Chesterfield Football Club's first-team coach and I'm a professional fellow.
"The gaffer's an ex-Sheffield United manager, he's an utter professional as well and we now represent Chesterfield. We'll be doing everything we can to get our players ready and up for the battle on Saturday and up for getting three points."
In a charged atmosphere, Morgan emphasised the importance of his side going out strongly to mark themselves on the game.
"We're the home team and I'm sure anyone who's seen us play at home will know that we always try to start aggressively," he said.
"Things don't always go to plan as the opposition will have their own game plan, you may have to adapt and change at times but certainly we'll be aiming to come out and start the game brightly and looking to go forwards and be positive."
