Cristiano Ronaldo added to his phenomenal tally of goals this season with a 23rd minute strike to help set up a semifinal over two legs against holders Sevilla after the Andalusian club saw off Villarreal on Tuesday.
"We didn't have any problem tonight," Mourinho said at a news conference.
"We won the tie without having to run much. We were compact in defence and we knew from the start they weren't going to get many chances."
The other semifinal is between 2009 winners Barcelona and Almeria, the Andalusian club who made it through to the last four for the first time by knocking out Deportivo Coruna on Wednesday. A depleted Barca lost 3-1 at second-division Real Betis on Wednesday but went through 6-3 on aggregate. The first leg of the semifinals is next week and the return leg the following week.
