John Sheridan has today been appointed manager of Chesterfield, two weeks after Martin Allen's departure.
The former Sheffield Wednesday player left League Two play-off side Carlisle United last Friday to rejoin the Spireites.
Sheridan was on a five game winning streak with the Cumbrians, with his last game ending 2-0 against Morecambe.
He joins the club with new assistant manager Glynn Snodin, who spent nine years as assistant to Simon Grayson.
The 54-year-old started his managerial career during his playing days as he became co-caretaker manager with David Eyres of Oldham Athletic in 2000.
He became caretaker manager of Oldham again in 2004, the last year of his playing career, before permanently taking the job in 2006.
After three years at the club, he was relieved of his duties in March 2009 and joined Chesterfield just three months later in June.
The former Republic of Ireland international spent three years in North Derbyshire and won the League Two title in 2011.
Unfortunately, the Spireites were relegated just a year later, but also won the Johnstone's Paint Trophy at Wembley in the same year following a 2-0 win over Paolo Di Canio's Swindon Town.
In September 2012, he was sacked as manager of Chesterfield after five weeks on gardening leave.
Spells with Plymouth Argyle, Newport County, Oldham Athletic followed before he took the job at Notts County.
Sheridan only spent 10 months with Magpies before being sacked after equalling a club record of nine successive defeats.
He joined Oldham for a fifth time in January 2017. The Latics were bottom of League One at the time, but the former midfielder saved the club from relegation.
After leaving Oldham once more in September of the same year, Sheridan took another survival job with Fleetwood Town in February of 2018.
He led the Cod Army to 14th place in League One by the end of the season, but left the club to join Carlisle United.
Sheridan now has another relegation battle ahead as Chesterfield currently lie in the National League relegation zone with 18 games of the season to go.
His first game in charge will be this Saturday at home to Bedford Town in the second round of the FA Trophy.
