The Ligue 1 Europa Conference League is one of the most prestigious European football competitions in Europe. The competition has been held every year since its inception in 2005 and is considered one of the top clubs' cup tournaments in the world.

To qualify for the Ligue 1 Europa Conference League, teams must play at least three games against their league opponents in the regular season. If a team wins all three matches, they will be automatically promoted to the next round of the tournament.

In addition to playing against their league opponents, teams also have the option to play in the UEFA Europa League, which is played by teams from other countries in Europe who do not belong to the top tier of English or Spanish football. This means that if a team plays well enough in the Ligue 1 Europa Conference League, it can potentially earn spots in the UEFA Europa League.

However, to compete for the Ligue 1 Europa Conference League, Lyon, Brest, and Strasbourg must win their respective groups in the regular season. The first two places in each group will determine which teams advance to the quarterfinals of the tournament. In the quarterfinals, teams will face off against the winner of the group stage and the runner-up of the group stage. If both teams win their respective matches, they will advance to the final. The final match will determine the champion of the tournament.

It's important to note that this is just a general overview of the Ligue 1 Europa Conference League and how teams can progress through the tournament. Each team will need to work hard to qualify for the tournament and perform well in the regular season to become a serious contender for the title.
