Chelsea beat Leicester 2-0 at Stamford Bridge on Saturday, to make it two wins from two games, Mourinho described the performance as "lazy" but says he saw glimpses of what his team are really capable of.
"Football is about adapting to everything, but the reality is that our way of thinking about football, the DNA we want in our team, is this one we are trying to show, maybe not for 90 minutes yet but we are showing in some moments,"
The Portuguese boss accepts his men still have plenty of hard work ahead, but believes things are moving in the right direction.
He added: "Everything feels good yes, but it is only two matches out of 38.
"The reality is not just that you win but that you show things, maybe not for 90 minutes and continuously, I can't expect more than that.
"We are also showing a different style of play, and we have the players to play that way, so it is good to have a certain identity.
"We started the second half at 0-0, but never lost our identity, we never started playing in a different way, we are a pass-and-move team when we have the ball, we are doing that, we believe in that.
"The players are enjoying it, obviously we need to be more intense, defensively as well, we need to pass more, attack the man with the ball more.
"We need to improve more in many details, but the basic things are there and we believe in that."
Mourinho singled out Branislav Ivanovic for praise saying the defender has the right mental attitude.
"He has been immense," he added.
"Ivanovic is strong going forward and is strong defensively. I think that right now I expect this from him because he is one of the ones from our important days, from the mental point of view he belongs to that strong base.
"I don't know if he has got the credit he deserves, but I don't think he worries too much about it. He is about 'select me to play, give me the right-back shirt and everything is good'. That is not a problem and for many years he has been performing at the highest level."
