Date of birth
Northern Ireland born Johnston has worked through the ranks of Fleetwood as he signed his first professional deal alongside fellow countryman Dylan Boyle in January 2020.
During his time at the club, Johnston was named in the League Football Education’s ‘The 11’, which acknowledges the football and academic progress of Under 18 players on apprenticeships at current EFL clubs.
In September 2020, Johnston made his debut against Carlisle United and has since been loaned out to Farsley Celtic, making 14 appearances and scoring one goal for the National League North side.
The midfielder extended his current Town contract in January 2021 as the 18-year-old agreed to stay in the Fylde Coast until the summer of 2022, with the club holding an option of a further year.
