Carlo Ancelotti's side have not won in their last two league games, losing to Saint-Etienne before drawing 1-1 with defending French champions Montpellier away from home without the suspended Zlatan Ibrahimovic.
The Parisian outfit, though, remain at the top of the league standings with 23 points from 12 matches ahead of Marseille, but only on goal difference.
Rennes are ninth in the table with 19 points from 12 matches, just four points behind PSG.
Frederic Antonetti's side are fighting for a European place and a victory in Paris will enhance their chances of achieving their target.
Possible starting lineups:
PSG: Sirigu, Van der Wiel, Thiago Silva, Alex, Maxwell, Thiago Motta, Pastore, Matuidi, Lavezzi, Menez, Hoarau
Rennes: Costil, Theopile Catherine, Biyik, Boye, Mavinga, M'Vila, Makoun, Pitroipa, Feret, Alessandrini, Erding
Sports Mole says: 3-1
