France Spending seven years in charge of
US Forbach in the
Championnat de France Amateur, Three years later, in 2014, the
Creutzwald native went back to France as the
Laval manager at the time,
Denis Zanko, contacted him for the assistant job, which he took and signed a one-and-a-half-year contract. Six months later, he left the Luxembourgish outfit by mutual agreement and took a ten-month managerial training course.
Africa One of Hesse's contacts, Michel Gruhn, put him in touch with then
Mali coach
Henryk Kasperczak, who hired Hesse with immediate effect as assistant since he knew him from his time with
FC Metz.
Young Lions Hesse was given the
Young Lions manager role ahead of the
2016 S.League as part of a coaching contingent summoned by
FAS technical director
Michel Sablon to go to Singapore. Even though the Frenchman arrived in Singapore in January, his official appointment as coach was deferred until he got his work pass one month later and was sanctioned to do business in the country. His first match in charge was a 1–0 triumph over
Balestier Khalsa before losing twice in a row to
Albirex Niigata S and
Geylang International by 5–0 and 2–0 goal deficits. Early in the
season, Hesse was also impressed with Albirex Niigata S and wanted the
Young Lions to model their style of play after Albirex Niigata's. Ahead of the
2017 S.League, Hesse left his post, having not been complacent with the club's last place finish. ==Personal life==
