Lokeren
In December 2007, Omer Golan got his transfer to Europe when the Belgian club Lokeren paid an estimated $1 million to his former club, Maccabi Petah Tikva. One of his demands in the contract is that he could leave the club if a bigger club offers him a contract. Several Belgian top clubs such as Anderlecht and Standard as well as some English clubs, were reportedly wanting to sign him, but he finally signed in Lokeren, most likely due to the significantly higher wages which were offered to him. In Golan's first season at Lokeren, the 2007–08 season, he scored 5 goals in 15 appearances. In his second season, he scored 6 goals in 29 appearances and in his last season with the club he scored 2 goals in 18 appearances. Overall in all club competitions he scored 13 times and made 6 assists in 64 games for Lokeren.

After an unsuccessful spell at Lokeren, Golan returned to Maccabi Petah Tikva. In his first season back he scored 10 goals and made 1 assist in 28 games in all club competitions. In the 2011–12 season he had a very poor season only scoring 6 times in 33 games and Petah Tikva also had a poor season as they got relegated after 21 consecutive seasons in the top flight. The next season, he won with Petah Tikva the 2012–13 Liga Leumit as the club got promoted back to the Premier League, Golan had one of his best seasons as he scored 18 league goals and was one of the most important players for the team in that season. On 13 March 2014, he retired from the game. He will be remembered as one of the greatest players in the history of Maccabi Petah Tikva, in 11 seasons with the club he made a total of 313 appearances and is the all time goalscorer for the club with 103 goals in all club competitions.
International career
Golan made his international debut for the Israel national football team when he came on as a 74th-minute substitute for Eyal Berkovich in a friendly against the Moldova national football team on 28 April 2004. His first international goal came on 9 February 2004 against the Croatia national football team, when he scored the final goal to tie the game at 3–3. On 17 November 2007, Omer Golan scored the winning goal for Israel against Russia, handing England a lifeline in their qualification group for Euro 2008, meaning England could still qualify; if Russia had won, qualification for England would be near impossible. Golan was, for a short period, proclaimed a hero by English football fans; but England lost the match to Croatia meaning they did not qualify for Euro 2008. According to Golan, before he scored against Russia, many thought that he was on the national team because of his strong friendship with Avi Luzon, then IFA chief and former owner of Maccabi Petah Tikva.
