Mourinho revelled in the success - a 2-0 win on the night earned a 3-3 aggregate draw and progress on away goals - and lauded all aspects of his side's performance.
"The players were open to the risk, they were open to the sacrifice," Mourinho told Chelsea TV.
"People in midfield they had to run miles. People in the defensive line, they had to cope with these big players with lots of space, which is always more difficult.
"People who create were always trying to create. The strikers went to the box well.
"Fantastic mentality by the boys and so, so happy for them."
