PSG head into the final round of Ligue 1 games this calendar year unbeaten domestically and with a five-point lead from nearest challengers 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.
At least they breathed life into their faltering Champions League campaign in midweek, a 3-0 win at Red Bull Salzburg calming fears that they might not make the knockout phase of Europe's elite club competition.
Even then, coach Luis Enrique suggested his team had played better in earlier games against PSV Eindhoven and Atletico Madrid, neither of which they won.
Lyon, who won seven consecutive Ligue 1 titles in the first decade of this century, have often been a thorn in PSG's side even if they have won just one of the last eight meetings of the clubs.
