Lazio boss Simone Inzaghi admits Rennes pushed them hard for their 2-1 Europa League win.
Jeremy Morel nodded Lille ahead from a free kick.
Substitute Sergej Milinkovic-Savic changed the game, scoring one goal and providing the assist for Ciro Immobile to win it 2-1.
The first half should've been better in building out from the back, Rennes sat back to wait for us and we couldn't find the strikers," Inzaghi told Sky Sport Italia.
We should've had more patience and we did better in the second half, winning an important game for us."
On Milinkovic-Savic, he continued: It was a good goal from Milinkovic-Savic, but regardless who plays, we need to work with our characteristics and we usually do it much better than this.
Naturally, Milinkovic and Luis Alberto are great players, but we ought to maintain our style and shape even without them. I took Danilo Cataldi off because he was on a yellow card.
We are pleased, as we lost the first game and now the group is wide open ahead of the very important double encounter with Celtic."
