Tapie, who oversaw Marseille's European Cup triumph, insists anything is possible in Lyon.
He told Le Figaro: "I will say in banality, but in football, in one match, anything is possible. Those who love football know it: anything can happen between two teams for 90 or 120 minutes of play. I know it better than anyone else since in 1991, before the final of the European Cup in Bari against Red Star, nobody gave them a chance.
"We had a crazy team, with Waddle, Mozer, Stojkovic, Papin ... All the best! And we went back with our heads down. This year, OM has nothing to lose against Atlético. So it will be played on the commitment of each other, on the shared desire in the team ... And the next day, we say that the best have won."
