Mourinho is set to make his emotional return to Stamford Bridge on March 16 for the second leg.
“We can go there with a legitimate ambition to go through,” he said.
“The most important thing is the result and we are ahead.
“It’s not obviously the result which ends the tie, it’s not 3-0 or 4-0, but no team is leading by two goals at this stage of the Champions League.”
“I have to control my emotions and have to be professional like I was today,” he added.
“In the tunnel, it is not a normal game for me – and it is not for them either – but when the game starts, it becomes normal for them and for me; they want to win and I want to win.
“At Stamford Bridge, I don’t expect anything other than people to be glad to have me back as we worked so well together.
“This time I will go back to a different dressing room, a different dugout and but I know normally Mourinho is lucky at Stamford Bridge.”
