Leonard joined the Nash in July from Glossop North End where he had a very successful 2016/17 campaign, collecting the managers`, players` and supporters` player of the year as well as the `golden boot` with the Evo-Stik League North outfit.
The 23-year-old former Huddersfield Town forward had a spell with Toolstation Northern Counties East League side Garforth Town whilst still on the Terriers` books and then joined Evo-Stik League South outfit Frickley Athletic in October 2014 after a spell with AFC Emley.
He bagged two early goals for The Nash on debut in a 4-0 victory against North Ferriby United on the opening day of the season.
After failing to maintain his place in John Flanagan's starting team, scoring just 2 more goals in his following fifteen appearances, the young forward has accepted a move to the New Bucks Head.
