Lazio coach Maurizio Sarri concedes they're in a form slump after defeat to Atalanta.

The Biancocelesti have collaped in recent weeks, as they went out of the Coppa Italia quarter-final to Juventus, were held to back-to-back 1-1 draws in Serie A and now suffer this 2-0 home defeat.

Sarri lamented: “We lost our heads after conceding the second goal. It wasn't a bad start, we had the chances to take the lead and then to equalise, but when we failed to convert them and then let in the second, we never recovered.

“There are battles during a season, we certainly won't surrender the war. There are 16 rounds to go, the table is tight and we cannot think of just giving up now. There are teams ahead of us who are better equipped, but that doesn't mean we won't try to the very end.

“Some of our key players lost sharpness after the Milan game and they had made the difference during that period of the season. At the moment, we are struggling to be sparkling and effective in attack, but they will get back there.

“We had the chances to score today and get back into the game, getting the feeling that if we had equalised, the inertia of the whole match would've shifted over to us.

“When Atalanta are in a mood like this, they are extremely difficult to face. I don't think we made it any easier for them, aside from after the second goal, and we were still in it until then."
