Lalatović came through the youth system of hometown club Red Star Belgrade.

Before moving abroad in the 2003 winter transfer window, Lalatović was named captain and made over 100 competitive appearances, winning four major domestic trophies with the Crveno-beli.
In January 2003, Lalatović was transferred to Ukrainian side Shakhtar Donetsk on a three-year deal.[1] He failed to make an impact with the club, being loaned to VfL Wolfsburg in early 2004. After returning to Donetsk, Lalatović made a couple of appearances for the club in the title-winning 2004–05 season. He later received a one-year ban from the Ukrainian FA for assaulting the referee after a game between Shakhtar-2 and Zorya Luhansk in October 2005.[2]
In the 2006 winter transfer window, Lalatović returned to his homeland and joined Zemun. He spent six months at the club, before joining OFK Beograd. Following the 2006–07 season, Lalatović retired from professional football, aged 29.

On 29 June 2015, Lalatović was officially presented as manager of Borac Čačak.[4] He led the club to a best-ever start to a league season by placing second after the initial 17 rounds. On 10 November 2015, Lalatović parted ways with Borac Čačak due to unpaid wages and bonuses to his players.[5]
On 11 November 2015, Lalatović was appointed manager of Vojvodina until the end of the 2015–16 season.[6] He extended his contract with the club for one more year on 11 June 2016.[7] However, Lalatović terminated his contract with the club by mutual consent on 17 December 2016.[8]

On 5 June 2022, Bosnian Premier League club Borac Banja Luka appointed Lalatović as manager.[13] He was victorious in his first UEFA Europa Conference League qualifying round game as Borac manager, winning 2–0 against Faroese club B36 Tórshavn on 7 July 2022.[14] Following a series of poor results, which culminated with a 1–0 defeat to Leotar, Lalatović resigned as manager on 26 August 2022.[15]
