Spireites defender Laurence Maguire will be welcoming older brother and former Sheffield United man Harry to the Proact on Saturday, with both hoping for a home win.
Prior to his transfer to Premier League side Hull City, Maguire senior had a successful three-year stint with the Blades, but Maguire junior is expecting some brotherly support for the Spireites on Sunday afternoon.
Laurence explained: "Yeah, my brother will be there. I've got him a ticket and he'll be there. He says he'll be supporting Chesterfield and backing me, I always back him so I think he'll be on my side."
With his brother onside at the Proact for the 2:15pm kick-off, Laurence knows that the pressure is on but that his side have a chance against the upwardly-mobile Blades.
"It's a big game for the fans," he said. "Hopefully we put on a good performance for the fans and get the three points. We need the three points and if we get off to a good start and can win the game.
"The fans will be buzzing, there will be a buzz around the ground before the game and after it.
