Early career in Serbia Milijaš began his playing career in the youth ranks of Belgrade-based
FK Zemun, where he progressed through to make it into their first team in 2000. He really began to establish himself in the middle of the park during the
2001–02 season and was a vital player for the club over the following seasons. In the
2005–06 season, he had his best goal-scoring start to a season, netting eight times by Christmas. This attracted attention from the country's biggest club and local rival,
Red Star Belgrade. Following his continuous impressive form for
FK Zemun, Milijaš signed for
Red Star Belgrade in January 2006. He ended his first season with Belgrade by winning both the
Serbian Superliga and
Serbian Cup with his new club. Milijaš won both trophies again with Red Star Belgrade the following season. He found appearances restricted by then-coach
Dusan Bajević, but gained more playing time with the arrival of
Boško Djurovski as the club's then-new coach. Milijaš was later promoted to the first team as a central midfielder for the following seasons, becoming a key member of the team as they went close to more domestic honours and regularly competing in European competitions. In the
2008–09 Serbian Superliga, he became Red Star Belgrade's top goalscorer with 18 league goals, 22 goals in all competitions, making him Serbian football's leading scorer in that season. Milijaš also won the league's Most Valuable Player Award, was voted into the
All Star Team, named 2008–09 Serbian Superliga Player of the Year, and broke into the
Serbia national football team. This form attracted attention from various clubs in Europe.
Wolverhampton Wanderers On 15 June 2009, Milijaš signed for newly-promoted Premier League club Wolverhampton Wonderers on a four-year contract for an undisclosed fee, approximately £2.6 million. He made his debut in August during the club's 2–0 opening day defeat against
West Ham, in which he was voted
Sky Sports' man of the match. Milijaš scored his first goal for Wolves with a long-distance strike to earn a 2–1 home victory against
Bolton in December 2009; before netting a second and final goal for the season against
Burnley two weeks later. Milijaš made twenty appearances in the Premier League in the 2010–11 season, scoring twice. He also matched that tally in the League Cup, scoring two penalties against
Southend and
Notts County. In a 3–3 home draw against
Tottenham Hotspur, Milijaš created two goals by assisting
Kevin Doyle's opening goal, and then winning a penalty for a second Doyle goal. He was also featured in the team's victory at Aston Villa as Wolves almost stayed up on the final day of the season. Milijaš made only sporadic appearances during the next season, but became a starter in November and December. However, this was halted when he was sent off in a 1–1 draw against
Arsenal for a challenge on
Mikel Arteta in December 2011. Wolves made an appeal to have this red card rescinded, including a unique press conference by then-manager
Mick McCarthy who showed slow motion replays from a number of angles, but the appeal was unsuccessful and the three-match ban was upheld. Following this dismissal he only made several substitute appearances in the final months as the club were relegated under caretaker manager
Terry Connor. Following the appointment of
Ståle Solbakken as coach of Wolves at the end of season, it was announced that Milijaš was available for transfer, having expressed a desire to play more regularly. On 30 August, his contract was terminated by mutual consent, allowing him to find a new club.
Return to Red Star Belgrade On 31 August 2012, one day after his departure from Wolves, Milijaš rejoined his former club
Red Star Belgrade when he signed a three-year deal. He scored his first goal against Radnički Kragujevac 1923 from a free-kick. On 13 April 2013, Milijaš scored a hat-trick against
Spartak Subotica.
Later career On 16 February 2015, Milijaš transferred to
China League One club
Hebei China Fortune. On 14 February 2016, he transferred to fellow
Nei Mongol Zhongyou of the same league. On 31 January 2017, Milijaš rejoined his club
Red Star Belgrade for a third time, this time on a half-year contract. An avid Red Star fan, he once again proved loyalty to his club and fans. The same year in April, Milijaš played his 200th match for Red Star Belgrade in a 2–1 league victory against
Spartak Subotica. On 19 May 2019, Milijaš played his last match for Red Star in a 3–0 victory against
Napredak. For nine years in Red Star, he played 170 matches, scored 49 goals and had 38 assists. Milijaš also won four trophies, with all four being
Serbian SuperLiga in 2006–07, 2013–14, 2017–18, and 2018–19 seasons. ==International career==
