Ligue 1 Preview: Top two meet, PSG host Guingamp
Marseille welcome Monaco to the Stade Velodrome on Sunday for a first-meets-second clash in Ligue 1.
Elie Baup's men are the only side in the French top flight with a 100 per cent record after three games, having taken maximum points from meetings with Guingamp, Evian TG and Valenciennes.
However, they face the sternest test yet of their title-winning credentials when Claudio Ranieri's big-spending outfit come to town just two points adrift at the top.
Boasting the likes of Radamel Falcao, James Rodriguez and Joao Moutinho, newly promoted Monaco eased to wins over Bordeaux and Montpellier in their opening two matches, but were held to a goalless draw at home to Toulouse last time out.
Reigning champions Paris Saint-Germain have endured a stuttering start to their title defence, taking just five points from their opening three games.
However, Laurent Blanc's side got their first win of the season at Nantes last time out, and will be confident of picking up another three points when they entertain Guingamp - who have lost their last two - on Saturday.
Lyon will be looking to get over their European heartache by bouncing back at bottom-placed Evian TG.
Remi Garde saw his team crash out of the UEFA Champions League in their play-off against Real Sociedad with a 4-0 aggregate defeat in midweek - a disappointment that came just days after Reims had put an end to their perfect domestic start.
Hubert Fournier's side will be full of confidence after their 1-0 win at the Stade de Gerland last time out, and they will hope to follow that result up with another win at home to Nantes on Saturday.
Rennes and Lille are two other teams to have started the Ligue 1 season well with six points from a possible nine, and their meeting at the Stade de la Route de Lorient is likely to be a tight affair.
Lille's last win came at home to Christophe Galtier’s Saint-Etienne, who will be hoping to bounce back when they host Bordeaux on Sunday.
At the other end of the table, Sochaux and Ajaccio go head-to-head at the Stade Auguste Bonal with both looking for their first wins of the campaign, while Alain Casanova's Toulouse visit Bastia.
Elsewhere, Montpellier travel to Nice and Valenciennes head to Lorient.
