Matic sees no reason for Chelsea to alter their approach given the manner of victory last week.
"It's a different game and we have to forget about last week," he tells the official Chelsea website.
"Each match is different, particularly when you're playing against a top side like Manchester City. As a team, we try to prepare for each game in the same way and hopefully we can go there and produce a similar performance to the league game.
"They are a very strong team that like to attack in front of their own supporters. I expect them to play in a similar way to normal, but we will have our own approach to the game. We played with an attacking style during the league game and we will try to do that once again to prove we can compete with them."
