At age five, Khalili began playing football at the local club Högaborgs BK. He made his senior debut for the side in 2002, aged 16, and attracted interest from several big clubs around Europe. He had a trial with the Scottish club Celtic FC but chose not to move abroad, on the advice of the Swedish international Henrik Larsson, who also had started his career at Högaborg. Tired of the interest surrounding him, Khalili took a one and half-year break from playing football between the summer of 2003 and the beginning of 2005. He ultimately signed a three year-deal with Helsingborgs IF in Allsvenskan. However, he had a hard time establishing himself at the club, enjoying loan spells at both Randers FC in the Danish Superliga and Bunkeflo IF in Superettan during the upcoming seasons. In December 2007 he joined IFK Norrköping on a permanent deal. The club had just won a promotion to Allsvenskan. The team struggled in the league play during the season of 2008 resulting in an immediate relegation to the second tier. Khalili would however establish himself as a key member of the squad during the following seasons, enjoying another promotion to Allsvenskan in 2010.
Top scorer
Between 2011 and 2013 he played as a regular in Allsvenskan for the club from the county of Östergötland, making 37 appearances whilst scoring 13 goals in the top tier. During the midseason of 2013 he attracted interest from his former club Helsingborgs IF, who completed the transfer of Khalili in August the same year. He continued his impressive scoring form during the 2013 season at his new club, eventually being crowned as the top scorer of Allsvenskan with 15 goals in total.
Years abroad
Before the 2014 season, he attracted interest from abroad, signing a loan deal with Al-Shabab in Saudi Arabia. He enjoyed a successful stint at the club, scoring a spectacular soloist strike in a 2-1 win against Al-Nassr in March 2014. He signed for Shanghai Dongya in the Chinese Super League during the summer of 2014 on a permanent deal. Khalili went on to make 9 appearances for the side, scoring twice, before being deemed surplus to requirements due to the international players policy in the league. He was subsequently released from his contract on 1 February 2015. Soon after, he signed a short time-contract with Baniyas, returning to his birth country United Arab Emirates. He featured in 8 games for the club during the spring, scoring twice, before leaving on a free in May 2015.
On 7 July 2015, he signed a four and half-year contract with the Stockholm-based club Hammarby IF in Allsvenskan. There he reunited with his former manager at IFK Norrköping, Mats Jingblad – now the sporting director of Hammarby. During the second half of 2015 and throughout the whole 2016 season, Khalili failed to impress then manager Nanne Bergstrand, subsequently only being used as a substitute player. He scored his first competitive goal for the club on 17 July 2016, in a 3-3 draw against Falkenbergs FF on home turf. After only making 5 appearances midway through the 2017 season, under the reign of new manager Jakob Michelsen, Khalili went out on loan to Brommapojkarna. The six month-deal with the Superettan club was announced on 11 August2017. He made his debut for the side only a few days later, coming on as a second half sub, in a 1–1 away draw against Varberg. Khalili ultimately made 7 appearances for Brommapojkarna, as they won promotion to Allsvenskan, but returned to Hammarby at the start of 2018. In January 2018, Hammarby switched manager once again with Stefan Billborn taking over as head coach. Khalili received much playing time during the pre-season and scored in a Svenska Cupen 3–3 draw against GAIS on 25 February. Khalili began the league play as a starter and scored a brace in the third round, as Hammarby won 4–0 against his former club Brommapojkarna on 16 April. He ultimately finished the 2018 season with scoring 3 goals in 21 league games, as Hammarby finished 4th in the table. On 20 February 2019, Khalili signed a one-year extension with Hammarby, with his new contract running until 2020.
International career
Imad Khalili won several caps for the Swedish under-17's, under-19's and under-21s in his younger days. In 2014, he accepted an offer to play internationally for Palestine, but withdrew from the squad due to an injury. He is still eligible to play for either Palestine, UAE or Sweden at senior level.
