OFK Beograd Mozzart Bet

The beginning

The club was founded in 1945 as Metalac but it is considered to be the successor of BSK, one of the most prominent football clubs in Kingdom of Serbia and later Kingdom of Yugoslavia. It was also the most successful club between 1923 and 1941, with five national champion titles. BSK played its first game on 13 October 1911 against Šumadija from Kragujevac and won 8–1.

In 1945, after World War II, the club was established under the name Metalac by some former members of BSK. This club carried the name until 1950, when it was renamed to BSK, but in the 1957 the club merged with TSK Šumadija to form OFK Beograd (Serbian Latin: Omladinski fudbalski klub, English: YFC – Youth Football Club).

The golden era

A two-decade-long "Golden Era" began when the club won the Yugoslav Cup in 1953. Three other Yugoslav Cup wins followed, in 1955 and the 1961–62 and 1965–66 seasons. The club was the Yugoslav First League runner-up twice, in 1954–55 and 1965–66. In the meantime, the club had changed its name once again. In 1957, the club was named OFK Beograd, once again in an attempt to attract spectators to the stadium, especially younger ones who often opted for either Red Star or Partizan. In that time, the players played elegant football and therefore got the nickname of "Romantičari".

The 1960s and the first half of the 1970s were years of European glory. OFK Beograd had participated eight times in European competitions. Their biggest success came in the 1962–63 European Cup Winners' Cup season, playing in the semi-final against Tottenham Hotspur, eventual champions. In the following ten years, teams such as Napoli, Feyenoord, Panathinaikos, Bologna FC 1909, FC Twente and Juventus also lost to OFK Beograd.

The silent fall

The Romantičari were not able to take advantage of their success on the domestic and European scene. After several successful seasons, a sudden fall occurred. During the 1980s, the club often changed leagues from the First Division to the Second.

Modern era

In the summer of 2003, they were back in European competition. They played in the UEFA Intertoto Cup. OFK defeated Estonian side Narva Trans at home by the score of 6–1, but UEFA cancelled the result because of a smoke bomb being thrown on the field during the game. Consequently, only the second leg result would count. OFK Beograd won in Tallinn with a score of 5–3. They were eliminated in the second round by Czech club 1. FC Slovácko, with a score of 4–3.

The club was back on the European stage in 2004. They started playing in the second round of the Intertoto Cup and eliminated Dinaburg. In the third round, OFK went on to play against Tampere United. OFK Beograd defeated their Finnish opponents and went on to play in the semifinals. They were eliminated by Atlético Madrid losing the first leg 1–3 at home with Aleksandar Simić scoring for OFK and Fernando Torres, Diego Simeone and Ariel Ibagaza scoring for Atlético, losing the second leg 2–0 in Madrid meant OFK were eliminated 1–5 on aggregate. Even though OFK were eliminated it was seen as an honour and a return to the club's glory days to have a European powerhouse such as Atlético play at Omladinski Stadium with world class talents such as Torres and Simeone.

In 2005, the club entered the UEFA Cup in the second round of qualifying losing to Lokomotiv Plovdiv on the away goals rule. In 2006, the club faced French side Auxerre in the UEFA Cup. In the first game, in Belgrade, OFK defeated their opponents by the score of 1–0 a goal from centre-back Miloš Bajalica in the 31st minute of play proving the difference, a great result considering Auxerre was then one of France's strongest clubs. In the second game OFK Beograd lost 5–1 with the result standing at 2–1 for Auxerre with ten minutes to play, a result which would see OFK Beograd eliminate Auxerre. However, the young OFK team capitulated in the last ten minutes of play conceding three goals and were eliminated 5–2 on aggregate. In the 2010 Europa League, OFK beat Torpedo Zhodino of Belarus 3–2 on aggregate and went on to play Galatasaray where they lost 7–3 on aggregate, coming back from two-nil down to draw 2–2 with late goals been scored by Miloš Krstić and Nenad Injac in Turkey against Galatasaray but ultimately losing the second leg 1–5 at home with Danilo Nikolić scoring the only goal for OFK.

OFK Beograd were relegated from the Serbian SuperLiga after finishing fifteenth in the 2015–16 season. The next season saw relegation from the 2016–17 Serbian First League after finishing bottom of the table. The club played in the Serbian League Belgrade in the 2017–18 season (their first season in the Serbian third tier), finishing in second place behind Žarkovo who were promoted to the Serbian second tier.

In November 2018 the "Klub prijatelja OFK Beograda" was formed (trans. "Club of Friends of OFK Beograd") with the goal of saving the club from becoming extinct. The KPO is made up of fans who want to see OFK return to its former glories competing at the very top of the first tier of Serbian football.

In their second year in the Serbian third division, OFK finished in fifth position on 46 points, with Grafičar being promoted to the second division. OFK did however manage to win the Belgrade Cup.
