After three years away from the Proact Stadium, Mark Crossley has rejoined Chesterfield as goalkeeping coach on a part-time basis.
He joins following the expiration of his contract at recently relegated League Two side, Notts County.
This marks Crossley's third spell with club, starting out in 2009 as part of John Sheridan's backroom staff.
The only goalkeeper to save a penalty from Matt Le Tissier became the club's oldest debutant back in 2009.
Crossley also celebrated winning the League Two title before retiring from playing in 2011 and having a stint as co-caretaker manager with Tommy Wright.
After leaving the Spireites in 2013, Big Norm joined Barnsley before returning to the Proact in 2015 as part of Dean Saunders' backroom staff.
The Welshman left for Notts County in 2016 becoming assistant manager to Sheridan. He also had a spell as caretaker manager during his three years at Meadow Lane.
Crossley told the club website: "It is great to be back at Chesterfield and I'm really looking forward to working with John again and his assistant, Glynn Snodin. It promises to be an exciting season and I can't wait to get started."
