Lazio boss Stefano Pioli admits Monday night's game with Fiorentina is massive for both clubs.
The pair are battling for Champions League qualification.
"This game means a lot because we are targeting the same objectives and are both going through a good period of form," said Pioli in his Press conference.
"We both like to play attacking football and take the initiative rather than be passive. The Viola are further ahead because this is their third year together.
"The table is tight up there and we have to focus only on our own results. We have 13 games left to do our best."
