Thus, for two seasons, he coached on weekends while Thierry Anti managed training on weekdays and obtained the best results in the history of the club: vice-champion in 1988 then champion of France in 1989 and finalist of the Cup.

Major financial efforts have been made by Ivry to obtain these results, in particular with the aim of achieving a good career in the Champions League.

But the preliminary round against the Israelis of Hapoël Rishon LeZion turns to fiasco (defeats 27-22 in Tel Aviv and 21–22 in Ivry) and the club is eliminated before having really started the competition.

Then in 2004, he became for the first time coach of the Tunisia national team with the objective of the 2005 World Men's Handball Championship organized at home.

Beaten by France in the bronze medal match, Tunisia finished in 4th place, the best result of a non-European nation at the time.

However, at the 2014 African Men's Handball Championship, Tunisia lost its title to the host country, Algeria, without however calling into question its mandate as head of the Tunisian team.
