The 'Special One' says there is still another game to go...
The Nerazzurri secured a one-goal lead going into the second leg, round of 16 clash after defeating Chelsea 2-1 at San Siro.
"Tonight's victory means a lot, and nothing at the same time. It is only the first half, and the second will be played in London," Mourinho told Rai after the match.
"On the pitch, there are things that we couldn't communicate to the players because the crowd was so loud.
Mourinho then went on to defend goalkeeper Julio Cesar who let in somewhat of a soft goal tonight.
"Julio Cesar is a great shot-stopper, he could have maybe done more with the goal he conceded, but on many occasions he has saved us.
"I will have to control my emotions for the return leg in London. We wanted to be aggressive and dominate the match, and our goals caused a reaction out of Chelsea."
In a seperate interview with Al Jazeera television, Mourinho said he was confident ahead of the second leg because of the incredible unbeaten home record he had while at Chelsea.
"We know Chelsea well at Stamford Bridge...Mourinho doesn't lose at Stamford Bridge!"
