Chesterfield manager Lee Richardson believes Tommy Lee has the opportunity to establish himself as the club's first-choice goalkeeper after snapping up the Macclesfield Town shot-stopper on a one-year deal.
The 22-year-old, who has been training with the Spireites during pre-season, made 67 appearances for the Silkmen.
He also featured in 14 games during a loan spell at Rochdale that culminated in a place in the side that lost the League Two play-off final to Stockport at Wembley in May.
Richardson told the club's official website: "Tommy's a goalkeeper that has gained lots of experience over the last couple of seasons, including a Wembley appearance.
"He's a good character, mentally strong and very agile and has the chance to establish himself at Chesterfield."
