Lazio may be 16 points below Inter, but Lucas Biglia is confident they can dent the hosts' title ambitions with a win at San Siro.
Despite a dismal first half of the season, Lucas Biglia is adamant Lazio have the quality to deal Serie A leaders Inter only their third defeat of the campaign on Sunday.
Lazio, having finished third and qualified for the Champions League last campaign, are a lowly 12th in the table after 16 games.
Stefano Pioli's side, who crashed out of the Champions League in the play-off round, are winless in their last seven league matches, although they did beat Udinese 2-1 in the Coppa Italia on Thursday.
