Luis Alberto says there's no excuses for Lazio's 2-1 defeat to Fiorentina on Monday night.
Jack Bonaventura struck the winner on the night, with Nico Gonzalez also failing with a penalty for the Viola.
"We didn't do enough," Luis Alberto told Sky Italia.
I really don't know what to say, it was a game where we did not deserve to be leading at half-time. In the second, despite it seeming like a lucky night for us, we still failed to make the most of it, wasted a counter-attack for 2-0 and then conceded straight away.
We have lost too many games recently and this was a very important fixture for the standings. We were not up to it today. We cannot give up now, there are still too many rounds to go, but the table is really tough now for Europe. We've got to talk less and train more."
