Milan, who are six points behind Serie A leaders and arch-rivals Inter after eight games, claimed a surprising win over Real at Santiago Bernabeu on Wednesday.
At the same time, Inter were held to a disappointing 2-2 home draw by Ukraine's Dynamo Kiev to stretch their winless streak in the Champions League to eight games.
"The Milan that won a historic game against Real has also lost an historic one at home against FC Zurich," Mourinho was quoted as saying by Football Italia.
"All that interests me is what I think. I didn't see Milan's game, but I am happy. Happy for (coach) Leonardo, for his players and for Italian football."
Inter lie at the bottom of Group F with three points, one behind Dynamo Kiev, Rubin Kazan and leaders Barcelona.
