The forward's 11th league goal of the season came after Fabian Ruiz cancelled out M'Bala Nzola's first-half effort at Stade Bollaert-Delelis.

PSG enjoyed an unbeaten first half of its domestic campaign, but was behind in the 36th minute.

Goduine Koyalipou flicked a corner towards the far post, where Nzola controlled before his low drive was too hot for Gianluigi Donnarumma to handle.

Luis Enrique's side levelled just before the hour mark with Barcola darting into the area, and squaring the ball for the unmarked Ruiz to slot home.

Barcola then completed the turnaround and snatched all three points with four points remaining, rounding off a swift counter by firing into the top corner.

"It was a very contested, very difficult match. All matches are tough, and it’s hard to attack an opponent who defends so well with character and aggression," Luis Enrique said after the game.

"We started well, with control, but the real problems came in the second half of the first period when Lens became more dangerous.

"The second half was at a higher level, with more chances. The rhythm wasn’t enough in the first half, and we realised we needed to search for more depth."

Ahead of the game at the Stade Bollaert-Delelis, PSG confirmed the arrival of Khvicha Kvaratskhelia from Napoli. 

Kvaratskhelia was, however, not part of the travelling squad for this match, but Luis Enrique expects the Georgian winger to be involved soon.

"We wanted to sign him for a long time," Luis Enrique said.

"He has experience, personality, and he knows how to score, dribble, and defend.

"It’s a very good signing, a great addition to an already excellent squad. I believe he will demonstrate his quality with us."
