Real struggled to a 1-1 draw with Real Zaragoza yesterday.
"We are not scoring many goals, that is the truth. Perhaps one of the differences compared to last season. In four chances we'd score three, in six, four, etc," said Mourinho.
"We scored goals with great ease and the only player that has kept a similar average is Cristiano, all the others have dropped in terms of the number of goals scored and obviously the team suffers because of that.
"The goals will come. If they don't come on Wednesday we hope that they come in the next match, but it is true that we are finding it hard to score goals, which was something that helped us score 100 points last season, the goal record and this season we're not doing it."
