The Tournoi des As (Tournament of Aces) was the ancestor competition of the current Leaders Cup, being held from 1988 to 1993.

At the end of the season, the top 4 teams from the top-tier level French League qualified.

The 2 losing teams of the first day would meet for the third place spot, while the two semifinals winners would compete for the cup title.

It featured the top eight placed teams of the top-tier level French League, at the end of the regular season's halfway point.

The competition was often highly disputed, producing a different winner every year, except in 2009, when Le Mans won its second title, after previously winning the 2006 edition.
