Key takeaways: 

• Lionel Messi netted his fourth Ligue 1 goal - and his 478th senior league goal.
• Paris St-Germain confirmed a record-equalling 10th French cup with four matches to spare despite being held by 10-man Lens - but fans exited early to celebrate outside the stadium without the players.

Lionel Messi's astonishing curled shot looked set to seal the win for the hosts, who needed just one point to clinch the league.

But despite Kevin Danso's dismissal for a second booking, Corentin Jean level for a spirited Lens late on.

It is Mauricio Pochettino's first league win as a boss.

He said: "We are going through a tough period with the fans, and we expect it will get better. We're in a democracy, and we take all protests. But we have to show respect for this cup."

Upset by the club's Champions League departure to Real Madrid, the club's ultras began to leave the stadium 15 minutes ere the final whistle rather than celebrate with the players.

The ground was cleared 10 minutes after full-time, and the players did not do a lap of honor afterward.

"I don't understand," midfielder Marco Verratti expressed. "I know that they were disappointed regarding Madrid, but you have to move on at some point."
