Arsenal defender William Saliba admits revenge was on their mind for victory over Lens.
The Gunners won their Champions League encounter 6-0 in London.
Saliba told Canal+: We're very happy. They beat us in the reverse fixture, so we knew they were a very good side. We wanted to get at them early tonight. We were efficient in front of goal and we defended well, so it was a great performance.
"We knew they weren't an easy team to face, they showed us that at their place. We can be proud of what we've done this evening.
When I come back to France, I want to win, so it left a bitter taste in the mouth. But today we won, qualified and finished top of the group. We want to finish the group stage in the best way possible against PSV.
When a team beats you, you want to beat them and that's what we've done tonight. We rewatched the tapes from the first game: what we did well, what we didn't. Today, it worked well. We had the fortune of playing at home, so that was easier for us."
