Paris: Kylian Mbappe scored in the 93rd minute as Paris St-Germain beat Rennes to go 16 points clear at the top of Ligue 1 before the weekend’s games.
The encounter looked to be heading towards a goalless draw, with the hosts missing a number of chances.
However, in the third of six minutes added on Lionel Messi got away from a defender before finding Mbappe, who fired home.
The victory means PSG have won 18 of their 24 league games, losing once.
Mbappe, 23, hit the post just before half-time and had the ball in the net in the second half, but it was ruled offside by VAR.
Second-place Marseille are at Metz on Sunday.
