Hernanes is confident Lazio will stay in the running for the Scudetto.
The Biancocelesti currently lie in second place, just three points behind Milan as the winter break approaches in Serie A.
"Our mentality is clear," he said. "We must think one game at a time and try to stay at the top for as long as possible.
"We'll see what our position is at the end of the season. We'll finish in a position that will make us happy."
