“As I already said, when you’re in the Champions League at this stage of the competition, there is no easy draw,” Edouard Mendy said at a press conference.
“Lille finished 1st [in Champions League group], which is an indicator of their performances.
“So it is not an easy draw, Lille are a great side. Granted, they are struggling a bit more in the league this year, however the season after winning a title are often complicated.
“But we can see that they’ll try their luck in the Champions League this year and they’ll do their best to get a result against us. So we must be vigilant and play our best football.
“Lille shocked the world of football last season, winning the Ligue 1 title, beating PSG by a point.
They have failed to build on their success this season though and are just 11th in the Ligue 1 table with just 36 points after 25 games.
Lille finished first in their Champions League group, ahead of RB Salzburg, Sevilla and Wolfsburg.
