Lazio coach Maurizio Sarri admitted relief after their Champions League win against Feyenoord.
Ciro Immobile scored the only goal of the night.
"We stayed in the game, also in difficult moments. We knew we had to suffer because they are a goal machine and tonight we managed not to let them score," Sarri told Sky Italia.
"We could have hurt them in the final 20 minutes. Hopefully, we won't pay a high price because some players had physical issues."
Sarri admitted injury concerns for Luis Alberto and Zaccagni.
We are a little concerned," Sarri admitted. We decided not to press their central defenders much because they use the goalkeeper so well," explained Sarri.
So we let them keep possession, especially after taking the lead."
