Chief executive Chris Turner has paid tribute to Jimmy Ryan following the midfielder's decision to join Fleetwood Town.Ryan, who was a free agent after coming to the end of his contract, has agreed a two-year deal with Fleetwood.
Turner said: "Jimmy made a great contribution during his time with us and was an important figure when we won the League Two title in the 2013/14 season.
"We are naturally disappointed to see Jimmy leave as we wanted him to stay. The previous management team talked to him about a new contract last season and those talks continued over the last few weeks. I am told that we matched the terms offered by Fleetwood, but Jimmy has chosen to go there because it is closer to his family home.
"I would like to take this opportunity to thank Jimmy for his services and wish him all the best for the future."
Ryan, 26, scored eight goals in a total of 100 appearances for the Spireites after signing in the summer of 2013.
