The Blues have been busy in the transfer window and have strengthened their attacking options with the addition of Eden Hazard, Oscar and Marko Marin.
And Di Matteo admits fans can now expect to see a different Chelsea at Stamford Bridge, in terms of faces and approach.
“I think what's most important now is to integrate the new players into the side,” Di Matteo told the club’s official magazine.
“Obviously, bringing in players with different abilities and qualities might change the face of our team a little bit as well, but we have to always find the right balance between attacking and defending.
“I think moving between the lines and rotation can be an attacking threat for us. We had only Juan Mata playing that role last year, although Raul Meireles played there a few times as well.
“It just gives us more options for the team. It makes us more difficult to be marked and more unpredictable.
“However, we also need width in the game, so it's not just always coming between the lines; it's about giving width to the team as well.”
The 42-year-old thinks that Chelsea have a lot to look forward to this season, but believes he is still under pressure despite landing the manager’s job on a permanent basis.
“The pressure is always there, whether you have won or not. It's a pressure job,” he added.
“I think we are all happy with what we achieved last season, but we have to understand that is part of the past now.
“Now, we have to look forward - and there is a lot of excitement. We have a lot of targets and objectives to achieve this season, competitions that are very difficult to qualify for, like the European Super Cup and the World Club Championship.
“It takes a long time to reach those competitions and it's hard to get there, so I'm looking forward to this season with a lot of excitement.”
