Real Madrid have a surprisingly poor record in Germany, suffering 16 defeats, six draws and winning just once out of the 23 games they played in the country.
Mourinho admitted that they will be hard-pressed to add another win to the tally when Real travel to play Dortmund in their third group game given the German champions' impressive home support.
He told UEFA's official website: "It will certainly be a difficult match but not because of our injured players - I don't think we are desperately short of players. We will have a team capable of putting in a good performance here. It will be a difficult match because Dortmund are difficult opponents.
"The reason Madrid have not thrived historically in Germany is down to the quality of the opposition. If they did not come from a country with a strong footballing tradition, it would be different. I saw that last season when we lost the semi-final 2-1 at Bayern, but this record will not have a psychological impact.
"It is always a difficult task here in Germany, as they have strong teams with ambitions similar to our own. That's how things are: German teams are always strong. We know how dynamic they are, how gifted and how quick they play, but they do have little weaknesses which we plan to exploit. We are not that worried about individual players, even though we know they have lots of good ones.
"The entire group is tough. You will not storm through this group by winning your first three games. Nor is it a group where you will break records and win 18 points.
"We know it will not be easy," explained the 24-year-old, speaking to reporters.
"But if we play our game, and continue to play the way we have done so far, hopefully we can get the win.
"We have been doing well lately. We started off badly in the league, but we feel good at the moment. We are happy with what we're doing and we always aspire to win every competition."
