Sunday's Ligue 1 clash between Paris Saint-Germain and Lyon, the two clubs who have taken turns dominating French football so far this century, pits the stuttering reigning champions against opponents who have hit a rich vein of form. PSG head into the final round of Ligue 1 games this calendar year unbeaten domestically and with a five-point lead from nearest challengers Marseille and Monaco at the top of the table. However, they have struggled to convince recently and have been held to draws in their last two domestic outings, against Nantes and Auxerre.
