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. His career started with Gordon Lee's Port Vale. He played two FA Cup games for the "Valiants" as a 17-year-old in the 1968–69 season, both First Round games with Shrewsbury Town in which he conceded one goal in both the original game and the replay at Vale Park. An emergency replacement for the injured Stuart Sharratt, he was so keen that he used to iron his bootlaces before playing. He was given a free transfer in May 1969 and moved into non-league football with Eastwood, and then Stafford Rangers. With Rangers he was a member of the 1972 FA Trophy winning team, following a 3–0 win over Barnet at Wembley Stadium. In 1973, he returned to the Football League, signing for Tony Waiters's Plymouth Argyle. The "Pilgrims" posted a 17th-place finish in the Third Division in 1973–74, before winning promotion with a second-place finish in 1974–75. They then held their own in the Second Division, finishing in 16th place in 1975–76. In August 1976, he played two games on loan at Oxford United; both games were League Cup clashes with Cambridge United. He was then loaned out to Ipswich Town. Aleksic left Home Park permanently when he was moved on to league rivals Luton Town in November 1976, who were managed by Harry Haslam. The "Hatters" finished sixth in 1976–77, four points behind promoted Nottingham Forest. Luton then dropped to 13th in 1977–78 under new boss David Pleat, and then finished 18th in 1978–79. He played 77 league games in his three years at Kenilworth Road. Aleksic was signed by First Division side Tottenham Hotspur in December 1978 for a fee of £100,000. The club posted a 14th-place finish in the 1979–80 season under the stewardship of Keith Burkinshaw. He faced competition between the sticks from Barry Daines and Mark Kendall. In one tie against Manchester United, notorious 'hard man' Joe Jordan broke his jaw in what was officially described as an 'accidental collision'. The injury left midfielderGlenn Hoddle to take Aleksic's place in goal for the rest of the match; despite this setback, Hoddle was untroubled in goal, and Spurs won 1–0 with Osvaldo Ardiles scoring the winning goal. 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. However, he soon lost his first team place to Ray Clemence, and was on the bench for the 1981 FA Charity Shield draw with Aston Villa. Spurs went on to finish fourth in 1981–82, but 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. He later emigrated to South Africa, and played for Wits University, before taking up employment at the Golfer's Club in Johannesburg.
