So the onus was on Neymar to deliver and he did so in a fine outing, ensuring his side moved top of the table prior to title rivals Lille facing Nice this evening.
We have taken a look at Neymar's performance.
📷 Neymar: Match Snapshot
⚽ ⏱️ 33' It was a calm and confident finish from Neymar to put PSG into the lead after Julian Draxler set him up, Facundo Medina having conceded possession in a dangerous area for Lens. The Brazil forward found the bottom corner with a right-footed effort.
Ignatius Ganago got a goal back for Lens and Neymar was denied his second goal of the game by a wonderful Wuilker Farinez save from his free-kick, but PSG were triumphant nonetheless.
Neymar was constantly involved. He had 103 touches, 26 contested duels, 12 successful duels, 32 passes into the final third and 10 touches in the box - all game-high figures.
〽️ Neymar: Rating Week-on-Week
Neymar came into this match having scored only once in his previous nine outings, which included a disappointing 6.5 FC Rating last time out against Man City.
His form has otherwise been good, though, with strong performances in both legs against Bayern Munich in the Champions League quarter-finals.
This display was good enough to earn him a 9.3 FC Rating, his best since scoring twice against Lorient on January 31 and an ideal response to a poor night against Man City.
Neymar: What Next?
Neymar will hope to have Mbappe back alongside him for a match that will determine the success of PSG's season.
Neither forward was at their best in the first leg, but this lively showing against Lens should serve as useful preparation and a confidence boost for Neymar.
