“In all honest, I didn't think we'd be challenging for the Scudetto," Lucas told Globoesporte.
“Our objective has always been to fight for Champions League qualification. Since I arrived at Lazio, the results have been very positive. Last year we won the Coppa Italia, now we are focused on the top four, but we'll fight it out now that we're up there.
“Juventus and Inter are the favourites, above all the Bianconeri have the experience of winning trophies and titles."
He added: “Our strength is that we've been working together continually for four years under (Simone) Inzaghi. I've been at Lazio for three seasons, but in recent months we've been able to win the Coppa Italia and Italian Supercup, which is not easy."
