Inter may have collected just seven points from a possible 21 so far this term, but Maicon insists they are still title contenders.
"We'll believe in the Scudetto until the very end," the Brazilian international told Sky Sport Italia.
"The win against Chievo on Sunday was crucial and we have to continue on this path if we are to climb the table."
Inter returned to winning ways with a 1-0 triumph at the weekend, but they'll face a tricky test at Atalanta on Wednesday.
The Bergamo boys are currently one point ahead of them in the standings – even with their six-point deduction.
Inter, who replaced Gian Piero Gasperini with Claudio Ranieri last month, are 16th in the standings and eight points behind surprise leaders Udinese.
Inter squad to face Atalanta: Julio Cesar, Castellazzi, Orlandoni; Cordoba, Chivu, Jonathan, Lucio, Maicon, Nagatomo; Alvarez, Cambiasso, Motta, Muntari, Obi, Sneijder, Stankovic, Zanetti; Castaignos, Milito, Pazzini, Zarate.
