A goalkeeper born to a Yugoslav father, he grew up in a small Serbian community in Chesterton, Staffordshire; he was a childhood friend of future England international Mike Pejic.
[5] Aleksic left Home Park permanently when he was moved on to league rivals Luton Town in November 1976, who were managed by Harry Haslam.
[11] The White Hart Lane club made a top ten finish in 1980–81, and also lifted the FA Cup with a 3–2 victory over Manchester City at Wembley.
Aleksic featured in both the original tie and the replay, which was won with a brace from Ricardo Villa and a scruffy goal from Garth Crooks.
[12] However, he soon lost his first-team place to Ray Clemence,[10] and was on the bench for the 1981 FA Charity Shield draw with Aston Villa.
Despite being an FA Cup-winning goalkeeper just one year previously, he dropped back into non-League football with Barry Fry's Alliance Premier League side Barnet in 1982, following a brief loan spell at former club Luton Town.
