Raymond Goethals, who coached Marseille to European Cup success in 1993, died on Monday at the age of 83, following a long illness.
Goethals was back at Marseille in 2002 to remember the 1993 win
He also led Anderlecht to win the Cup Winners' Cup in 1978, and coached his native Belgium between 1966 and 1976.
Marseille were stripped of their 1993 title because of match-fixing by their former club president Bernard Tapie.
But Tapie has led the tributes to Goethals, describing him as "an extraordinary man".
Tapie admitted: "I am really sad, very sad. He was much more than just a coach.
"He had a nose for detecting young talent, and he was able to adapt to any situation on the pitch.
"On the human side, he was a fabulous guy who joked around with the players, which showed that he had their respect."
During his time in charge of the national side, Goethals led Belgium to third place in the 1972 European Championships.
He also took Standard Liege to two league titles and a Cup Winners' Cup final, and enjoyed more success after returning to Anderlecht.
