I used to have a soft spot for PSG from around 1993 to 2003 in the Rai to Ronaldinho era. Players like Lama, Okocha, Djorkaeff, Ngotty, many interesting players. Now they're obviously disgusting.
If I had to pick a French team I suppose it would be something Juve-linked like Saint Etienne. I would have picked Strasbourg but it's just another franchise club these days.
