PSG were looking to take advantage of another slip-up by title rivals Lens, who were held to a 1-1 draw away at Strasbourg on Friday to go two games without a win.

Luis Enrique's side duly got the job done with Barcola heading in from a Lee Kang-in cross on 37 minutes for his ninth goal of the season.

It was not a full-strength PSG, with Ousmane Dembele again out injured along with Fabian Ruiz and Joao Neves, while skipper Marquinhos was among the players rested.

Doue came off the bench in the second half and won a penalty with just over 10 minutes remaining, but his kick was kept out by Le Havre goalkeeper Mory Diaw diving to his right.

Diaw also produced a fine reaction save from Nuno Mendes while PSG goalkeeper Matfei Safonov made a key stop to deny Issa Soumare at the other end.
