Liverpool have conceded three 90th minute goals in this Champions League group stage, goals that have cost them four points and qualification. Last night's late winner for Fiorentina was another blow admitted Benitez.
"To see Aquilani and Torres were positives from this match," said the boss.
"I think it was clear today was a difficult game, but we conceded another goal in the last minute and we are really disappointed with the three late goals we have conceded in the competition.
"When you lose in this way, having worked so hard and had chances, the only positive is that maybe we will be more focused in future if necessary.
"But I don't think we lack concentration. Tonight was a mistake and it's something that can happen."
