Paris SG vs Nancy , PSG will play against Barcelona in Champions League next week , so i think most of players will not play tommorow due to their next game , i will bet for Under 3.5 Goals.
Bastia vs St Etienne , i will bet for a Draw or for St Etienne to win .
Dijon vs Nice , i will bet foe Over 1.5 Goals .
I will follow you on PSG and St Etienne. For PSG, is for the reasons you mentioned. Although they have a great margin over Barcelona, it's still Barcelona, so they need to be careful and ready for that game. They should manage the game if they start winning this one, so under 3.5 looks like a good option to me. As por St Etienne, not that I trust them lately, since they are not doing very well, but Bastia is doing even worse, so a draw or away look like a decent option.
Paris St-G v Nancy
Under 3.5 Goals @ 1.7
SC Bastia v St Etienne
Draw or Away @ 1.32
