Monaco moved above Marseille and into second place on goal difference, but direct rivals Lyon in fourth, Nice in fifth and sixth-placed Strasbourg all won on Saturday to move one point behind Monaco with three matches left.

Rennes replied early in the second half through 17-year-old striker Mohamed Kader Meïté before Lyon's fourth goal from Georges Mikautadze, which was the best of the night.
