The Giallorossi go to Milan looking to maintain their 100 per cent start to the season.
"The Nerazzurri sure are a strong team with talented players," Garcia said.
"They have the advantage of playing at home. But that doesn't change anything for me.
"I've always said to my players that we have to try to win all 38 matches, both home and away. I hope tomorrow's match turns out to be a great game.
"We're relaxed even though we're top. The most important thing is the team remains calm. It's obviously easier to be so when you win.
"We're expecting 5,000 fans from Rome. The San Siro will be almost full and it will be a great atmosphere. It would obviously be better to have the three points at the end.
"It's too soon to talk about targets like [the Scudetto]. Tomorrow's match is important but no more than the others that are to come. Every match represents three possible points and we'll see how things go further down the line.
"We're top for the moment and this has to help the team, simply by giving them more confidence in their play. We know anything can happen in a match against Inter. I think we're very well prepared on the mental side and we need to fight with everything: if we do that we'll definitely get a good result."
