Torres was preferred to Samuel Eto'o to make his 100th Chelsea start and netted his 38th and 39th goals for the Blues following his £50million move from Liverpool before Eden Hazard added a late third.
The World Cup-winning striker has been much-maligned, mainly due to his hefty price tag, but Mourinho has belief in the ability of the Spaniard and was pleased to see his selection justified.
"What boosts him is the confidence he knows I have in him," Mourinho said.
"Samuel played a very good game against Cardiff and scored the winning goal.
"I thought Fernando was adapted to this game. I put faith in him and he answered well.
"It's good for him, it's a good feeling to score goals, winning goals in the Champions League."
