Early coaching career

Troussier soon moved into management after gaining his coaching licences and achieved his first coaching position with the French Football Federation where he was allowed to manage a National football centre football club called Institut National du Football de Vichy or more commonly known as INF Vichy. The team were allowed to participate in the third tier and given exemption from promotion or relegation so the young players could develop. In his time with the team he led them into the 1983–84 league season where they came second within their group.^[3] The following season Troussier would coach CS Alençon in the French fourth division and spent three seasons learning how to manage an amateur football club.^[4]

He would return to his former club Red Star 93 in the 1987–88 league season as their manager. In his time with the club he would guide them to second within the group and promotion to the second tier at the end of the 1988–89 league campaign.^[5] He would, however leave the club on 30 June 1989 to join second-tier club Créteil on a caretaker basis until 1 October 1989 when Bernard Maligorne took on the management position.^[6]

Move to Africa

Troussier's first move away from France started with Ivory Coast top division football club ASEC Mimosas where in his debut season he won the league championship.^[7] This would soon be followed by two further league titles and an endearment towards the country, which saw him gain citizenship with Ivory Coast. With his impressive run at club level the Ivory Coast national football team hired him as their manager in hopes that he could replicate his success with the national team. He was assigned to qualify for the 1994 FIFA World Cup, however he failed to achieve this and soon left his post to move to South African football club Kaizer Chiefs.

After a brief period with Kaizer Chiefs Troussier moved to Moroccan football club Fath Union Sport and led them to the 1995 Coupe du Trône.^[8] His time with Fath Union Sport also saw him experience relegation to the second tier with them, however he remained with the club for several seasons until he was offered a chance to return to international management with Nigeria to replace Shaibu Amodu as they attempted to qualify for the 1998 FIFA World Cup. Entering the job halfway through qualifying he led them into four games throughout the campaign as Nigeria qualified, however the Nigeria Football Federation decided to relieve Troussier of his duties and ultimately let highly experienced coach Bora Milutinović lead them into the tournament due to his experience of already managing three different nations in a World Cup at that time.^[9]

Troussier quickly found a new job managing another African nation in Burkina Faso where he was assigned to coach them in the 1998 African Cup of Nations, which they were hosting. In a short period of time he made the team genuine title contenders until they were beaten by Egypt 2–0 in the semi-finals. Burkina Faso ultimately finished fourth after losing to DR Congo in the third-place match, nevertheless the result meant it was their highest ever finish at the time.^[10] His stint at Burkina Faso would impress the South African Football Association, who offered him the job of leading South Africa to the 1998 World Cup. He would replace Jomo Sono, who, despite leading South Africa to the final of the 1998 African Cup of Nations as a caretaker manager, was not given a permanent position. Troussier, however was not able to galvanize the squad as he had done with Burkina Faso and the team were knocked-out in the group stages. After the tournament he would leave Africa, but before he did he was nicknamed as the "White Witch Doctor" for his overall successful legacy towards African football. However, his role as coach of South Africa remains a highly controversial topic, in which former defender Mark Fish, who played in the 1998 World Cup, later blamed Troussier for the failure.^[11]

Move to Asia

In 1998 Troussier replaced Takeshi Okada to coach Japan and was assigned to improve upon the nation's previous results at the 1998 FIFA World Cup as they prepared to co-host the 2002 FIFA World Cup. Having to use a translator, he struggled to get what he wanted from the players as they were knocked out of the 1999 Copa América within the group stages.^[12] The disappointing performance within the tournament gathered a negative reaction from the Japanese media, which saw Troussier go for a more youthful approach and take the reins of the under-20 team as they participated in the 1999 FIFA World Youth Championship.^[13] The Japanese team had a successful campaign and were runners-up within the tournament. He continued to take control of Japan's youth teams when he managed the under-23 team in the 2000 Summer Olympics and led them to the quarter-finals.^[14] The majority of that team would then go on to be called up to the 2000 AFC Asian Cup and win the tournament.^[15] With this success, Troussier went into the 2002 FIFA World Cup with confidence and led Japan to the final 16, making it at the time Japan's best ever finish within the competition.^[16]

In July 2003 Troussier was appointed as the new manager of Qatar and was assigned with qualification for the 2004 AFC Asian Cup with the hope of repeating the success he previously had with Japan.^[17] Initially his reign went smoothly with a successful qualification campaign and a team selection that once again employed a youthful approach as well as several naturalized players.^[18] The tournament itself turned out to be a disappointment that saw Qatar finish bottom of their group. Along with his disappointing start to the 2006 FIFA World Cup qualification campaign, Troussier was ultimately fired from his position.^[19]

Return to France and Africa

On 27 November 2004, Troussier returned to France to manage Ligue 1 team Olympique de Marseille. His time with the club would see him have a tumultuous relationship with the senior players, particularly French international player Bixente Lizarazu.^[20] A fifth-place finish at the end of the season saw Troussier replaced by Jean Fernandez. He returned to Africa and became the head coach of the Moroccan national team, having taken over after the country's failure to qualify for the 2006 World Cup. However, he was fired after two months in charge by the Royal Moroccan Football Federation due to a difference in opinion.

Return to Asia

From 2005, after a stint with Morocco, Troussier would stay away from football and was confirmed to have converted to Islam around 2006.^[1] In March 2008, he returned to Japan to manage FC Ryūkyū a Japanese third-division team, before he was replaced by compatriot Jean Paul Rabier. On 22 February 2010, he returned to management with Chinese Super League side Shenzhen Ruby F.C. on a three-year contract.^[21] He would once again enforce a youthful team selection; however this would relegate the team, making them the first top-tier champions to be relegated since the foundation of professional football in China.^[22] He would remain with the club while they were in the second tier; however after mounting criticism he would alienate himself from the fans after the fourth-round league match versus Chongqing F.C. when in a local TV interview Troussier fired out against criticism and doubt from fans and urged them "not to come to the game or him". Shenzhen Ruby won the match, however former players who were forced to leave by Troussier in his efforts to force youth into the team Li Fei and Chris Killen scored for Chongqing F.C. in their first return to Shenzhen and physical confrontations took place after the match among fans, staffs, players and even Troussier himself.^[23] He further alienated his relationships with the squad and staff on 25 August after a defeat to Chengdu Tiancheng F.C. saw the club's hopes of promotion vanish and he provided a statement that he would take leave back to France on a "regular holiday under his contract".^[24] The club's supporters would believe the board sent him on leave hoping that the indignity would see him resign rather than compensating him the 1 million euros per year in his contract. He returned from his holiday and managed the club throughout the 2013 Chinese league season, where he was unable to gain promotion.

Troussier is widely believed to be the first-choice replacement as coach of the Malaysia national football team after the Football Association of Malaysia didn't renew former coach K. Rajagopal's contract after it expired in December 2013. He was said to have agreed a MYR5 million annual salary with the FAM.^[25] However, the deal fell through when he faced some disagreements with the Football Association of Malaysia.^[26]

On 30 June 2014, Troussier became manager of CS Sfaxien of Tunisia.^[27] On 28 September 2014, Troussier quit CS Sfaxien.^[28]

In April 2018, he was one of 77 applicants for the vacant Cameroon national team job.^[29]
