The Romans head into Sunday's game against Lecce at the Stadio Olimpico second in the standings, five points behind league leaders AC Milan despite their goalless draw in Genoa last time out.
"A draw is a good result considering we were playing away from home and against a good side like Genoa," said defender Biava.
"Now we have two games at home against Lecce and Sampdoria and we will try to get as many points as possible.
"We are in a great position in the standings and we could not have asked for more at this stage of the campaign.
"But the scudetto is not a realistic aim for us.
"We just have to focus on doing well and try to finish in the top four in order to play in the Champions League next season."
Lazio will fancy their chances of claiming a win against Lecce with the Romans having only lost once at the Stadio Olimpico this season.
Moreover, Lecce have the leakiest defence in the competition with 35 goals given away in 18 games.
Lecce travel to the Italian capital having won just once in their last 10 matches.
Thursday's 1-0 defeat to Bari marked their 11th loss of the campaign and left Lecce in 19th place, three points behind safety.
Lecce coach Luigi De Canio will be desperate for his team to change that trend on Sunday.
Lazio welcome back coach Edy Reja, who served a one-match touchline ban in midweek.
The hosts will be without suspended defender Andre Dias and injured midfielder Francelino Matuzalem, who is sidelined for a month.
Lecce will have to overcome the absence of midfielder Guillermo Giacomazzi, who serves a one-match ban.
