Lazio coach Maurizio Sarri admits their top four chances are in doubt.

Sitting in eighth place, Lazio host Atalanta this weekend.

"We have shown solidity, but tomorrow we play against a team with incredible attacking potential. There isn't room for mistakes," Sarri said.

“I don't know if we have a chance to qualify for the Champions League. For now, we are focused on our growth.

"We are improving, but we must be more consistent. The result depends on small details."

Sarri also was asked about Luiz Felipe as his deal runs down.

“I don't know if he will stay," the coach admitted. “But I know the club want it, the lad is improving and he is giving us the idea that he can still develop."
