Veteran striker Jack Lester has revealed he will leave Chesterfield when his contract expires at the end of the season.
The fans' favourite will end a six-year association with the club following the Spireites' final npower League Two fixture of the season against Exeter at the Proact Stadium on April 27.
He told the club's official website: "I've loved it and I've had an amazing relationship with the fans. It's been really special and I'm sad to go."
When asked what message he had for the Chesterfield supporters, an emotional Lester said: "Just a thank you really, I know my family is really grateful for everything. My mum and dad come and they've loved coming here, just a massive thanks really.
"I think with their support I've played some of the best football of my career. I've had bad games here and they've stuck by me, so thanks for that."
Lester joined Chesterfield from Nottingham Forest in 2007 and has scored 83 goals in 194 league appearances for the Blues.
His goals helped fire the Spireites to the League Two title during the 2010/11 campaign and last season the 37-year-old was part of the squad that won the Johnstone's Paint Trophy at Wembley.
Chief executive Chris Turner had said in January that he was confident of sorting a new deal for Lester, who has struggled to secure a starting role in Paul Cook's team this season but still leads the scoring charts with nine goals in all competitions.
