The Blues meet the league leaders at the Emirates Stadium on Monday, December 23 and a win would see them leapfrog Arsene Wenger’s side at the summit of the table.
However, Mourinho knows it is only the formative stages of the 2013/14 season and will not be reading too much into the result if Chelsea do happen to topple Arsenal who were beaten 6-2 by Manchester City on Saturday.
"I like the fact we will go there with this distance (between the teams), because it brings even more ingredients to the game," he told Chelsea TV.
"However, I don't think in this league it will become a crucial game, if we leave Arsenal with five points difference or top of the league.
"I don't think it will make a big difference in terms of what is going to happen in the future because the league (this season) is like this."
