After three defeats in four games before the international break and a traumatic Champions League exit, PSG began the end-of-season run-in with a crushing win at the Parc des Princes.

Messi and Mbappe combined to set up Neymar for the opening goal on 12 minutes as the Brazilian struck for just the sixth time in another injury-plagued campaign.

Mbappe then doubled the advantage with a neat finish inside the near post, but Terem Moffi gave Lorient
hope early in the second half after punishing a defensive mix-up.

The Nigerian beat an uncertain Marquinhos to a loose pass from Achraf Hakimi, poking beyond Gianluigi Donnarumma.

With Lorient threatening to get back into the game, Mbappe restored PSG's two-goal cushion by drilling home from 20 metres to take his league goals tally to 17, one behind Monaco's Wissam Ben Yedder.

Mbappe teed up Messi to crash in a fourth via the underside of the crossbar on 73 minutes, moments after Sergio Ramos came on for a first appearance since January 23.

Neymar and Messi were both whistled by supporters in PSG's last home game. This time it was Ramos who was jeered following a nightmare first season in Paris blighted by a calf problem.

Mbappe nearly capped a sensational performance with a hat-trick, his shot grazing the post after a scorching burst into the box.

He instead turned provider in the final minute, exchanging passes with Neymar to send the Brazilian racing through to complete a 14th win in 15 home games for Mauricio Pochettino's side.

PSG hold a 12-point lead over Marseille, who reclaimed second place with a 4-2 win at Saint-Etienne in a game that was rescheduled from Saturday following heavy snowfall.
