Luke Armstrong came through the ranks at Middlesbrough before a short spell within the youth sides at Birmingham City. After being released from the Blues in 2015, Armstrong earned his first taste of Scottish football with Cowdenbeath.

Following a short stint with the Blue Brazil, Armstrong joined Northern Premier League side Blyth Spartans, where he netted 23 goals in 42 appearances at Croft Park. His performances attracted one of his predecessors as he returned to the Riverside Stadium.

Armstrong continued his goalscoring form on loan at Gateshead before stints at Accrington Stanley, Salford City, Hartlepool United, and Harrogate Town. The forward netted 29 times in 103 appearances for the latter before completing a move to Carlisle United in 2024.

The Steelmen overcame a host of competition North and South of the border for the 28-year-old’s signature, with Armstrong choosing Fir Park as his preferred destination.
