In the final round of the 2020-2021 Ligue 1 season, Rennes won their first title in over two decades and secured their place in the top flight once again. However, their joy was short-lived as they lost to Ajaccio, who were relegated from the league for the first time this season.

Rennes' victory came on the back of a strong display by Antoine Griezmann, who scored twice against Ajaccio in the final minutes of the match. The French forward's goal proved to be the turning point in the game, as it set up a dramatic comeback for the team.

However, the story didn't end there. Despite their success, Rennes faced a tough task in the relegation play-offs. They defeated Toulouse in the semi-finals before losing to Ajaccio in the final. This defeat was a blow for the team, but it also gave them a chance to learn from their mistakes and improve.

The team has since gone on to win another title in the second half of the season, securing their place in the top flight once again. While Rennes may not have been able to repeat their success, they have certainly shown that they can compete at a high level again. With a new manager in place and a talented squad at their disposal, Rennes could potentially make a serious push for a return to the Champions League next season.
