Inter won last night at the San Siro through Diego Milito's lone strike and Mourinho believes the club now can be regarded again as a European force.
"If Inter don't reach Madrid or even the semi-finals, for sure this year we have lifted the huge mental block of playing in the Champions League," he said.
"Inter have no fear of playing in the Champions League anymore and this is a result that will always stay.
"I cannot say if we will win the Champions League this year. There are another seven teams who want to win it as much as we do, but for sure next year, when Inter enter the Champions League again, they will be free of this mental block."
