The French football league system has undergone significant changes in recent years, with the introduction of Ligue 1 as the top tier of professional football in France. The new league format was introduced in 2014 and features 20 teams competing for the title.

In the first season after the introduction of Ligue 1, Rennes and Nice were promoted from the second tier of French football to the top flight. This marked a significant achievement for both clubs, who had been struggling to maintain their status in the lower leagues for many years.

After their promotion to the top flight, Rennes and Nice faced stiff competition from other teams in the league. However, they proved to be formidable opponents, winning several matches during the season. They also managed to score goals at a high level, which helped them to gain momentum in the league table.

Despite their success, both Rennes and Nice still have a long way to go before they can claim victory in the top flight. They will need to work hard to improve their performances and build a strong team that can compete with some of the best teams in Europe.

Overall, the promotion of Rennes and Nice to the top flight of French football is a testament to the hard work and dedication of these two clubs. With continued improvement and success on the pitch, it's clear that Rennes and Nice have what it takes to continue climbing the ladder and achieving success in the top flight of French football.
