Marseille's triumph, however, was later tainted by charges of match-fixing that saw the club relegated to the second tier and stripped of their 1992-93 Ligue 1 title, while Tapie was sent to jail.
But according to the Croatia legend, a footballer could not ask for a better employer than the disgraced former l'OM chief.
"Recently I went to Marseille for the 25th anniversary of winning the European Cup. We were a great team and had the best president!" he told Croatian TV show "Vecernji pressing."
"He bought a game for us and then we even got a bonus for that victory! And in the end he got punished (in jail, suspended from football) and us players profited!
"As I arrived to Marseille, I was young and ready, and I played with Rudi Voller, who was older and didn't have to prove himself any more, so he was not selfish and allowed me to score as much as I can. That helped me a lot."
Boksic never represented Croatia at a World Cup, missing the chance to shine in 1998 through a knee injury he described as "torture".
He is now looking forward to seeing the likes of Ivan Rakitic star in Russia, although he is concerned that Croatia's indiscipline could ruin their chances.
"Rakitic has surprised me a lot, even training him in national team, I never believed he could reach the level he has reached," he added.
"Croatia have great players but they need to be more disciplined. They don't have a leader to push them when things are not working as they should."
Boksic added that Croatia could use a player like Sergio Ramos, who has been known to straddle the line between legal and illegal maneuvers.
"Take the Champions League final for example," Boksic said. "It was decided by [Mohamed] Salah's injury. Sergio Ramos knew what he had to do and he never even got a yellow card!
"His move in the final was just as valuable as Bale's scissor-kick goal. And without those kinds of players you can not build a champion team!"
