Internazionale coach Roberto Mancini says a win against Juventus on Sunday evening would be a sign of intent by his team.
The Nerazzurri host Massimiliano Allegri's men knowing that a win would open an 11-point gap from the Bianconeri.
And Mancini has urged his players to be fully focused ahead of one of the season's most important fixtures.
"It's an important match because we're playing the team that won the last four league titles," Mancini told reporters.
"The mental aspect is crucial and we must make sure we get off to a good start and are totally focused. Beating Juventus now could show us whether we're able to stay up there at the top.
"A win tomorrow would be great for the morale, which is important for all teams.
"It's a long, hard season for all of us and anyone can lose or draw over the next 31 matches. I don't think anyone will go and win them all. There are some teams who are on form at the moment but it's impossible to win them all.
"We're second in a tight table with Juventus, Roma and Napoli behind us. We need to play relaxed but with the utmost concentration because there are hidden dangers in every single game.
"Nearly all our guys played two games with their national sides and Medel only got back yesterday. Jovetic is in fairly good shape. He's taken part in the last three training sessions and is much better now."
