Ambitious Leam Richardson has been handed a new two-year deal at League Two champions Chesterfield.
The Spireites assistant manager re-joined Paul Cook, who he worked with at Accrington Stanley, in the summer of 2013.
He had a year left on his current contract but has been rewarded for playing his part in the club’s title success and a return to League One.
“The club’s ambition matches mine and I am keen to help Paul Cook achieve further success following our League Two title win,” said Richardson.
“With the tremendous backing we have received from the board, I can only see us going forward as a club and it’s great to be a part of that.”
Chesterfield chief executive Chris Turner said that Richardson’s new deal tied him to the club for the same period as Cook.
He said: “We have a great management team in place and we felt it was the correct decision to ensure that Paul and Leam were both secured on contracts until 2016.”
While defender Nathan Smith, whose contract at the Spireites is set to expire, has agreed a return to Yeovil Town on a two-year contract.
Smith signed for Chesterfield from the Glovers in 2011 and made 68 league appearances during a three-year stay at the Proact.
He scooped the player of the season gong at the club’s 2012/13 awards but injury halted his progress this campaign - the 27-year-old made just 14 league appearances.
Yeovil manager Gary Johnson confirmed the deal and revealed he had done his homework on the former Potters Bar Town player.
He said: “After discussions with Terry Skiverton and Darren Way, who Nathan played under during his first spell at the club, we were all happy to bring Nathan back to the club.
“I am sure all the supporters will remember Nathan’s style of play and we all look forward to welcoming him back to Huish Park at the start of July.”
