>Bastia
One of the historical corsican clubs meaning there will be regional rivalries and violence and constant chaos with ownership and finances. That's just how they roll in Corsica.
The pitch can get horrendous because of the hot weather too, sometimes games are pretty much played on dirt.
>Boulogne
I know absolutely nothing about them, they get promoted to Ligue 2 and had some good days in the 90s, I was too young to remember that. Sorry :c
>Clermont Foot 63
Clermont is one of THE rugby cities in France. The local rugby club, ASM, is one of the best clubs in France and one of the better clubs in Europe. For decades, that caught all the love of the city and football had very little presence.
IIRC CF63 was created in the mid 90s and only became professionnal in the late 2000s. They're kind of a Ligue 2 mainstays although they did play two seasons in Ligue 1 recently, then dropped and barely escaped relegation to National. Currently in a bit of a financial hole because they are expanding on their delightfuly lobsided stadium. I will forever miss the absurdity of assymetrical Gabriel Montpied. Pic related.
>Dunkirk
A pretty recent arrival into Ligue 2. IIRC they got promoted in 2022. Then they were pretty bad in the first half of the 22-23 season. Then they moneyballed their way through the winter transfer window. The second half of their 22-23 season was the best of ANY club in a first or second division in the top 6 european leagues, it was INSANE to witness. They seemed ready to be a yo-yo-club between National and Ligue 2 and with one transfer window they became a promotion contender. They've made the promotion playoff every time since but always came short.
Also their stadium is tiny, is built pretty low and that's a problem because it's a very windy town so they have to learn to play without too many crosses otherwise their big plans could be thwarted by a random gust of wind.
