Chesterfield have completed the signing of midfielder Jonathan Smith from League Two club Stevenage on a three-month loan.
The experienced midfielder has been described as "capable of popping up with the odd goal but focusing his play on getting amongst the opposition and breaking up the play".
He started his career at Morecambe, but after failing to get into the team, Smith moved to Forest Green Rovers. He made 134 appearances and scored 18 goals for Rovers.
After a season with York City, the 31-year-old joined Paolo Di Canio's Swindon Town for the 2011-12 season.
He played an important part in the Robins' League Two title win that season and he was also part of the squad that lost 2-0 to the Spireites in the Johnstone's Paint Trophy final.
Smith left Swindon at the end of that season and spent another year with York before moving to Luton Town in 2013. The Conference Premier title followed two seasons later.
He spent five years with the Hatters before joining Stevenage in August 2017.
The Chesterfield boss was very happy with his new acquisition after years of being frustrated by the midfielder.
"Over the years he's a player who's annoyed me and frustrated me and he's not someone I've liked," said Allen, "He's very competitive, full-on committed and plays with passion and desire."
"I suppose it's these traits that I've loved and hated at the same time when he's been in opposing teams. Things have had to change."
Smith will hope to go straight into the squad for Saturday's game at the Proact Stadium, where the Spireites host Gateshead in hope of ending their eight-game winless run in the National League.
