Didier Drogba and Soloman Kalou may have departed, but Chelsea have moved to bring in Belgian playmaker Eden Hazard from Lille and Germany midfielder Marko Marin from Werder Bremen, who could both yet be joined by Porto's Brazilian frontman Hulk.
Di Matteo feels it is very much a case of evolution, not revolution at Stamford Bridge, and said: "I don't think it will be an overnight thing. I wouldn't expect radical changes."
He added: "I would like us to be a good team that can compete and always in the frame for the targets this club has.
"I don't think there'll be a big overhaul of how we approach the games, new players will be integrated into the team and we will try and get the best out of them.
"I don't see any reason to change. I am the way I am - this is me. The way I operate is me and that's not going to change in the future.
"I have my way to communicate with the players and I will continue with that.
"My job is too make them feel confident and to put their talent for the service of the team and try to win games.
"We certainly have to make up ground [in the Premier League] because we finished 25 points behind the leaders so that's going to be a big job."
