Vladimir Petkovic gave Fiorentina credit for their performance, but could not help being upset at Lazio’s incorrectly disallowed goal.
The Biancocelesti were beaten 2-0 in Florence  after going down to nine men, as Cristian Ledesma and Hernanes saw red.
“We gifted them the first half and could not get hold of the game because Fiorentina were very aggressive and pushed high up the field. We were not at 100 per cent,” he told Sky Sport Italia.
“In the second half we dominated until the decisions went against us. The goal was not offside, clearly. I am told there might also have been a penalty for a Juan Cuadrado handling offence, but I don’t know.
“There were also some yellow cards that I did not understand. In any case, these are not alibis, as we should’ve done better.
“We must not diminish the credit owed to Fiorentina for their performance, as they were much more attacking and deserved the victory. Had it not been for these incidents then they might’ve deserved it even more.”
