Michel played for AS Aix between 1964 and 1966. He then moved to FC Nantes where he played from 1966 until his retirement in 1982. Michel also played 58 times for the France national football team, and was selected for their 1978 World Cup squad.
Michel had two stints with Morocco, the first being between 1995 and 2000. His second stint, beginning in 2007, was short-lived with a poor showing at the Africa Cup of Nations 2008 where Morocco left in the first round. This resulted in his sacking from the post in February 2008.
From 2001 to 2002, he coached Tunisia. He was fired when Tunisia exited the 2002 African Cup of Nations in the first round after failing to score a single goal.
After the 2006 World Cup he joined the Egyptian club Zamalek. He left the club in 2007 to return to Morocco.
Sundowns
In 2008, he was appointed coach of Mamelodi Sundowns in South Africa. He left in March 2009 after being chased by an angry mob demanding his resignation.
El Zamalek
After two years turned back to El Zamalek on 30 August 2009 and on 30 November 2009 El Zamalek officials have fired the French coach due to negative results, the team was 15 points behind bitter rivals Al Ahly in the Egyptian league.
On 10 December 2010, Michel was hired head coach of the Equatorial Guinea to lead the team for 2012 Africa Cup of Nations they will co-host with Gabon. He suddenly resigned from his post on 19 October 2011, with the Africa Cup of Nations three months away, because he said he could not have the best players in the country, but five days later he was rehired thanks to the dismissal of Sports Minister Ruslan Obiang Nsue. On 21 December 2011, he resigned as coach of Equatorial Guinea again, citing interference from a "third party" as the reason for his departure.
Kenya
On 28 August 2012, Michel was named by the Football Kenya Federation as the head coach of the Harambee Stars, taking over from James Nandwa, who was acting as manager on a caretaker basis. Barely four months later, he resigned, stating that he "could not find an amicable agreement within the deadlines regarding my compliance with several provisions of the contract". The FKF has also stated that they were disappointed with his attitude especially in looking down towards local tournaments, even describing the 2012 CECAFA Cup as useless and sent Nandwa to handle the team as interim coach.
Death
Henri Michel died on 24 April 2018, aged 70. The cause of death was not disclosed.
